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
provide two pseudo-differential input pairs or four
single-ended inputs. The MCP3208 is programmable
to provide four pseudo-differential input pairs or eight
single-ended inputs. Differential Nonlinearity (DNL) is
specified 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
protocol. 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
respectively. 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.
