Key Features
- 8-input analog multiplexer with SPI-selectable gain from 1 V/V to 32 V/V allows a single PGA to replace 8 discrete fixed-gain amplifier channels in data-acquisition front ends
- 12 MHz gain-bandwidth product supports signal frequencies up to 375 kHz at unity gain, making it suitable for audio, vibration, and process-control measurement bandwidths
- SPI-compatible digital interface enables gain and channel selection from a microcontroller in under 1 µs, facilitating fast multiplexed scanning across 8 sensor inputs without external relays
Applications
The MCP6S28-I/SL serves multi-channel sensor data-acquisition systems where 8 different analog inputs must be selectively amplified and digitized by a single ADC, reducing chip count and PCB area compared to 8 separate fixed-gain amplifiers. Industrial process controllers and test instruments use its SPI gain control to dynamically adjust measurement range from 1x to 32x within microseconds, accommodating sensors with widely varying output levels on the same board. It also fits medical monitoring and weigh-scale applications that require software-adjustable gain to optimize ADC resolution across different load or signal ranges.

Frequently Asked Questions
How many analog input channels does MCP6S28-I/SL support, and what gain range is selectable via SPI?
The MCP6S28-I/SL supports 8 analog input channels selectable via SPI, with programmable gain settings of 1, 2, 4, 5, 8, 10, 16, and 32 V/V. This 32:1 gain range allows the same chip to condition a 100 mV sensor output up to the full-scale 3.3 V ADC range at 32x gain, or pass a 3 V signal at unity gain, without any hardware gain-setting resistors.
What bandwidth does MCP6S28-I/SL provide at unity gain, and how does this limit channel scan rate in a multiplexed data-acquisition design?
The MCP6S28-I/SL has a 12 MHz gain-bandwidth product, which equals 12 MHz of bandwidth at unity gain (1 V/V) and approximately 375 kHz at 32 V/V maximum gain. In a multiplexed scan across all 8 channels, the settling time to 0.1 % accuracy at 12 MHz bandwidth is roughly 60 ns per channel, enabling aggregate scan rates exceeding 1 MSPS when paired with a fast 12-bit ADC — well above the 10 kHz bandwidth of typical industrial process signals.
When would a designer choose MCP6S28-I/SL over a fixed-gain instrumentation amplifier in a multi-sensor panel monitor?
A designer would prefer MCP6S28-I/SL in a multi-sensor panel monitor when 8 different sensor types — such as thermocouples (millivolt output), pressure transducers (100 mV full scale), and current shunts (10 mV full scale) — must share a single 16-bit ADC. Switching gain from 1x to 32x via SPI in under 1 µs lets each channel use the full ADC dynamic range, whereas 8 fixed-gain amplifiers would require separate resistor networks, 8 additional IC packages, and manual recalibration if sensor types change.
