MCP6S91/2/3

Single-Ended, Rail-to-Rail I/O, Low-Gain PGA

Description

Features

• Multiplexed Inputs: 1 or 2 channels

• 8 Gain Selections:

The Microchip Technology Inc. MCP6S91/2/3 are

analog Programmable Gain Amplifiers (PGAs). They

can be configured for gains from +1 V/V to +32 V/V and

the input multiplexer can select one of up to two chan-

nels through a SPI port. The serial interface can also

put the PGA into shutdown to conserve power. These

PGAs are optimized for high-speed, low offset voltage

and single-supply operation with rail-to-rail input and

output capability. These specifications support single-

supply applications needing flexible performance or

multiple inputs.

- +1, +2, +4, +5, +8, +10, +16 or +32 V/V

• Serial Peripheral Interface (SPI^™)

• Rail-to-Rail Input and Output

• Low Gain Error: ±1% (max.)

• Offset Mismatch Between Channels: 0 µV

• High Bandwidth: 1 to 18 MHz (typ.)

• Low Noise: 10 nV/√Hz @ 10 kHz (typ.)

• Low Supply Current: 1.0 mA (typ.)

• Single Supply: 2.5V to 5.5V

The one-channel MCP6S91 and the two-channel

MCP6S92 are available in 8-pin PDIP, SOIC and MSOP

packages. The two-channel MCP6S93 is available in a

10-pin MSOP package. All parts are fully specified from

-40°C to +125°C.

• Extended Temperature Range: -40°C to +125°C

Typical Applications

• A/D Converter Driver

• Multiplexed Analog Applications

• Data Acquisition
