MCP3004/3008

2.7V 4-Channel/8-Channel 10-Bit A/D Converters

with SPI Serial Interface
Features Description
10-bit resolution The Microchip Technology Inc. MCP3004/3008
1 LSB max DNL devices are successive approximation 10-bit Analog-
1 LSB max INL to-Digital (A/D) converters with on-board sample and
hold circuitry. The MCP3004 is programmable to pro-
4 (MCP3004) or 8 (MCP3008) input channels
vide two pseudo-differential input pairs or four single-
Analog inputs programmable as single-ended or ended inputs. The MCP3008 is programmable to pro-
pseudo-differential pairs vide four pseudo-differential input pairs or eight single-
On-chip sample and hold ended inputs. Differential Nonlinearity (DNL) and Inte-
SPI serial interface (modes 0,0 and 1,1) gral Nonlinearity (INL) are specified at 1 LSB. Com-
Single supply operation: 2.7V - 5.5V munication with the devices is accomplished using a
simple serial interface compatible with the SPI protocol.
200 ksps max. sampling rate at VDD = 5V
The devices are capable of conversion rates of up to
75 ksps max. sampling rate at VDD = 2.7V 200 ksps. The MCP3004/3008 devices operate over a
Low power CMOS technology broad voltage range (2.7V - 5.5V). Low current design
5 nA typical standby current, 2 A max. permits operation with typical standby currents of only
500 A max. active current at 5V 5 nA and typical active currents of 320 A. The
Industrial temp range: -40C to +85C MCP3004 is offered in 14-pin PDIP, 150 mil SOIC and
TSSOP packages, while the MCP3008 is offered in 16-

 MCP3004/3008
6.0 APPLICATIONS INFORMATION
6.1 Using the MCP3004/3008 with
Microcontroller (MCU) SPI Ports
With most microcontroller SPI ports, it is required to
send groups of eight bits. It is also required that the
microcontroller SPI port be configured to clock out data
on the falling edge of clock and latch data in on the ris-
ing edge. Because communication with the MCP3004/
3008 devices may not need multiples of eight clocks, it
will be necessary to provide more clocks than are
required. This is usually done by sending leading
zeros before the start bit. As an example, Figure 6-1
and Figure 6-2 shows how the MCP3004/3008 can be
interfaced to a MCU with a hardware SPI port.
Figure 6-1 depicts the operation shown in SPI Mode
0,0, which requires that the SCLK from the MCU idles
in the low state, while Figure 6-2 shows the similar
case of SPI Mode 1,1, where the clock idles in the high
state.
As is shown in Figure 6-1, the first byte transmitted to
the A/D converter contains seven leading zeros before
the start bit. Arranging the leading zeros this way
induces the 10 data bits to fall in positions easily manip-
ulated by the MCU. The MSB is clocked out of the A/D
converter on the falling edge of clock number 14. Once
the second eight clocks have been sent to the device,
the MCU receive buffer will contain five unknown bits
(the output is at high impedance for the first two
clocks), the null bit and the highest order 2 bits of the
conversion. Once the third byte has been sent to the
device, the receive register will contain the lowest order
eight bits of the conversion results. Employing this
method ensures simpler manipulation of the converted
data.
Figure 6-2 shows the same thing in SPI Mode 1,1,
which requires that the clock idles in the high state. As
with mode 0,0, the A/D converter outputs data on the
falling edge of the clock and the MCU latches data from
the A/D converter in on the rising edge of the clock.

6.5 Utilizing the Digital and Analog
Ground Pins
The MCP3004/3008 devices provide both digital and
analog ground connections to provide additional
means of noise reduction. As is shown in Figure 6-5,
the analog and digital circuitry is separated internal to
the device. This reduces noise from the digital portion
of the device being coupled into the analog portion of
the device. The two grounds are connected internally
through the substrate which has a resistance of 5 -10.
If no ground plane is utilized, both grounds must be
connected to VSS on the board. If a ground plane is
available, both digital and analog ground pins should
be connected to the analog ground plane. If both an
analog and a digital ground plane are available, both
the digital and the analog ground pins should be con-
nected to the analog ground plane. Following these
steps will reduce the amount of digital noise from the
rest of the board being coupled into the A/D converter.

Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.

Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchips Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

Microchip is willing to work with the customer who is concerned about the integrity of their code.

Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as unbreakable.

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchips code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
