Key Features
- 6 selectable analog input channels with SPI-programmable gain (1x, 2x, 4x, 5x, 8x, 10x, 16x, 32x), enabling a single IC to replace a multi-channel fixed-gain amplifier network
- Rail-to-rail input and output swing on a 2.7 V to 5.5 V supply allows direct connection to ADC inputs referenced to either 3.3 V or 5 V without additional level shifting
- 14-pin TSSOP package with SPI control interface (CS, SCK, SDI) integrates channel selection and gain programming into one chip, reducing BOM count in multi-sensor data-acquisition systems
Applications
The MCP6S26-I/ST is used in data-acquisition front ends for industrial instrumentation, multi-channel sensor interfaces, and automated test equipment where each input channel may carry signals of varying amplitude requiring different gain settings. Its SPI-programmable gain and input multiplexer allow a single ADC to digitize six different sensor signals—such as thermocouples, strain gauges, and pressure transducers—at optimized resolution without switching discrete amplifiers. The compact TSSOP-14 package suits portable instruments and PCBs with tight space constraints.

Frequently Asked Questions
What gain settings are available on the MCP6S26-I/ST and how are they selected?
The MCP6S26 supports 8 programmable gain settings: 1x, 2x, 4x, 5x, 8x, 10x, 16x, and 32x. Gain and channel selection are both configured over the 3-wire SPI interface by writing to the on-chip control register, allowing the host MCU to change gain between conversions in microseconds without analog switches or resistor networks.
How does the MCP6S26-I/ST's 6-channel multiplexer simplify a multi-sensor data-acquisition system?
Instead of using 6 separate fixed-gain amplifiers—each with its own resistor network—the MCP6S26 routes any of its 6 input channels to a single output amplifier with SPI-selected gain. This reduces the analog front-end to one 14-pin IC plus bypass capacitors, saving board space and lowering BOM cost while allowing dynamic range optimization for sensors spanning millivolt to volt-level outputs.
In a 3.3 V system with a 12-bit ADC, what is the effective input range of the MCP6S26-I/ST at maximum gain?
At 32x gain with a 3.3 V rail-to-rail supply, the output swing covers approximately 0 V to 3.3 V, meaning the input signal range at maximum gain is roughly 0 V to 103 mV (3.3 V / 32). This is well-suited for amplifying low-level thermocouple or load-cell outputs before digitization by a 12-bit or 16-bit ADC.
Can the MCP6S26-I/ST coexist with other SPI peripherals on a shared bus?
Yes. The MCP6S26 uses a standard SPI interface with an active-low chip select pin (CS), operating at clock frequencies up to 10 MHz. Multiple MCP6S26 devices or other SPI peripherals can share the same MOSI, MISO, and SCK lines, with each device individually addressed by its dedicated CS line, enabling multi-channel PGA arrays on a single SPI bus.
