MCP3204/3208
Description
The
devices are successive approximation 12-bit Analog-
to-Digital (A/D) Converters with on-board sample and
hold circuitry. The MCP3204 is programmable to pro-
vide two pseudo-differential input pairs or four single-
ended inputs. The MCP3208 is programmable to pro-
vide four pseudo-differential input pairs or eight single-
ended inputs. Differential Nonlinearity (DNL) is speci-
fied at ±1 LSB, while Integral Nonlinearity (INL) is
offered in ±1 LSB (MCP3204/3208-B) and ±2 LSB
(MCP3204/3208-C) versions.
Communication with the devices is accomplished using
a simple serial interface compatible with the SPI proto-
col. The devices are capable of conversion rates of up
to 100 ksps. The MCP3204/3208 devices operate over
a broad voltage range (2.7V - 5.5V). Low current
design permits operation with typical standby and
active currents of only 500 nA and 320 µA, respec-
tively. The MCP3204 is offered in 14-pin PDIP, 150 mil
SOIC and TSSOP packages. The MCP3208 is offered
in 16-pin PDIP and SOIC packages.
