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

devices are successive approximation 10-bit Analog-

to-Digital (A/D) converters with on-board sample and

hold circuitry. The MCP3004 is programmable to

provide two pseudo-differential input pairs or four

single-ended inputs. The MCP3008 is programmable

to provide four pseudo-differential input pairs or eight

single-ended inputs. Differential Nonlinearity (DNL)

and Integral Nonlinearity (INL) are specified at ±1 LSB.

Communication with the devices is accomplished using

a simple serial interface compatible with the SPI

protocol. The devices are capable of conversion rates

of up to 200 ksps. The MCP3004/3008 devices operate

over a broad voltage range (2.7V - 5.5V). Low-current

design permits operation with typical standby currents

of only 5 nA and typical active currents of 320 µA. The

MCP3004 is offered in 14-pin PDIP, 150 mil SOIC and

TSSOP packages, while the MCP3008 is offered in 16-

pin PDIP and SOIC packages.

• ± 1 LSB max DNL

• ± 1 LSB max INL

• 4 (MCP3004) or 8 (MCP3008) input channels

• Analog inputs programmable as single-ended or

pseudo-differential pairs

• On-chip sample and hold

• SPI serial interface (modes 0,0 and 1,1)

• Single supply operation: 2.7V - 5.5V

• 200 ksps max. sampling rate at V_DD= 5V

• 75 ksps max. sampling rate at V_DD= 2.7V

• Low power CMOS technology

• 5 nA typical standby current, 2 µA max.

• 500 µA max. active current at 5V

• Industrial temp range: -40°C to +85°C

• Available in PDIP, SOIC and TSSOP packages
