MCP3201

2.7V 12-Bit A/D Converter with SPI Serial Interface

Features

Description

• 12-bit resolution

The Microchip Technology Inc. MCP3201 device is a

successive approximation 12-bit Analog-to-Digital

(A/D) Converter with on-board sample and hold

circuitry. The device provides a single pseudo-differen-

tial input. Differential Nonlinearity (DNL) is specified at

±1 LSB, and Integral Nonlinearity (INL) is offered in

±1 LSB (MCP3201-B) and ±2 LSB (MCP3201-C)

versions. Communication with the device is done using

a simple serial interface compatible with the SPI

protocol. The device is capable of sample rates of up to

100 ksps at a clock rate of 1.6 MHz. The MCP3201

device operates 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

300 µA, respectively. The device is offered in 8-pin

MSOP, PDIP, TSSOP and 150 mil SOIC packages.

• ±1 LSB max DNL

• ±1 LSB max INL (MCP3201-B)

• ±2 LSB max INL (MCP3201-C)

• On-chip sample and hold

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

• Single supply operation: 2.7V - 5.5V

• 100 ksps maximum sampling rate at V_DD= 5V

• 50 ksps maximum sampling rate at V_DD= 2.7V

• Low power CMOS technology

• 500 nA typical standby current, 2 µA maximum

• 400 µA maximum active current at 5V

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

• 8-pin MSOP, PDIP, SOIC and TSSOP packages
