Description
The Microchip Technology Inc. MCP3202 is a succes-
sive approximation 12-bit Analog-to-Digital (A/D)
Converter with on-board sample and hold circuitry. The
MCP3202 is programmable to provide a single pseudo-
differential input pair or dual single-ended inputs. Differ-
ential Nonlinearity (DNL) is specified at ±1 LSB, and
Integral Nonlinearity (INL) is offered in ±1 LSB
(MCP3202-B) and ±2 LSB (MCP3202-C) versions.
Communication with the device is done using a simple
serial interface compatible with the SPI protocol. The
device is capable of conversion rates of up to 100 ksps
at 5V and 50 ksps at 2.7V. The MCP3202 device oper-
ates 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 375 A, respec-
tively. The MCP3202 is offered in 8-pin MSOP, PDIP,
TSSOP and 150 mil SOIC packages.
