DESCRIPTION

V_REF

The Microchip Technology Inc. MCP3204/3208

devices are successive approximation 12-bit Ana-

log-to-Digital (A/D) Converters with on-board sample

and hold circuitry. The MCP3204 is programmable to

provide two pseudo-differential input pairs or four sin-

gle-ended inputs. The MCP3208 is programmable to

provide four pseudo-differential input pairs or eight sin-

gle-ended inputs. Differential Nonlinearity (DNL) is

specified at ±1 LSB, and Integral Nonlinearity (INL) is

offered in ±1 LSB (MCP3204/3208-B) and ±2 LSB

(MCP3204/3208-C) versions. Communication with the

devices is done using a simple serial interface compat-

ible with the SPI protocol. The devices are capable of

conversion rates of up to 100ksps. The MCP3204/3208

devices operate over a broad voltage range (2.7V -

5.5V). Low current design permits operation with typi-

cal standby and active currents of only 500nA and

320µA, respectively. The MCP3204 is offered in 14-pin

PDIP, 150mil SOIC and TSSOP packages, and the

MCP3208 is offered in 16-pin PDIP and SOIC pack-

ages.
