MCP6S21/2/6/8  
Single-Ended, Rail-to-Rail I/O, Low Gain PGA  
Description  
Features  
• Multiplexed Inputs: 1, 2, 6 or 8 channels  
• 8 Gain Selections:  
The Microchip Technology Inc. MCP6S21/2/6/8 are  
analog Programmable Gain Amplifiers (PGA). They  
can be configured for gains from +1 V/V to +32 V/V and  
the input multiplexer can select one of up to eight chan-  
nels through an 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)  
• Low Offset: ±275 µV (max)  
• High Bandwidth: 2 to 12 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 MCP6S21 and the two channel  
MCP6S22 are available in 8-pin PDIP, SOIC and  
MSOP packages. The six channel MCP6S26 is avail-  
able in 14-pin PDIP, SOIC and TSSOP packages. The  
eight channel MCP6S28 is available in 16-pin PDIP  
and SOIC packages. All parts are fully specified from  
-40°C to +85°C.
