The MCP6S26-I is a six-channel programmable gain amplifier (PGA) from Microchip Technology that combines a 6-channel input multiplexer with a digitally controlled gain amplifier, all controlled via a simple SPI serial interface. This integrated approach eliminates the need for discrete amplifier and multiplexer combinations, simplifying design and reducing board space. The MCP6S26 supports eight programmable gain settings: +1, +2, +4, +5, +8, +10, +16, and +32 V/V, providing flexibility for a wide range of signal conditioning requirements. The input multiplexer selects one of six single-ended input channels, which is then amplified by the PGA to the selected gain level. With a bandwidth of 10 MHz at unity gain and a slew rate of 10 V/µs, the device can handle fast-changing signals while maintaining accuracy. The rail-to-rail input and output architecture allows full utilization of the supply voltage range, maximizing dynamic range in single-supply applications. The SPI interface supports clock speeds up to 20 MHz and features daisy-chain capability, enabling multiple MCP6S26 devices to be controlled through a single serial interface. A shutdown mode is available for power-sensitive applications, reducing supply current to microamp levels. The ‘I’ suffix indicates the industrial temperature range of -40°C to +85°C, ensuring reliable operation in demanding environments.

The MCP6S26-I consists of two main functional blocks: a 6-channel input multiplexer and a programmable gain amplifier, both controlled through the SPI interface. The input multiplexer is a CMOS analog switch array that connects one of the six input channels (CH0 through CH5) to the amplifier input. Channel selection is done by writing to the channel register via SPI. The PGA core is a non-inverting operational amplifier with a digitally controlled feedback network that determines the gain. The gain is set by switching different resistor values in the feedback path, creating precise gain ratios of 1, 2, 4, 5, 8, 10, 16, and 32 V/V. The resistor network is laser-trimmed during manufacturing to achieve tight gain accuracy and low drift. The rail-to-rail input stage uses a complementary PMOS/NMOS input pair to accept signals from the negative supply rail to the positive supply rail. The output stage is also rail-to-rail, capable of driving the output to within millivolts of both supply rails. The SPI interface receives commands for channel selection, gain setting, and device configuration. The daisy-chain mode allows the serial output of one device to feed the serial input of another, enabling control of multiple PGAs with a single chip select line. A shutdown command places the device in a low-power state, with the output going to a high-impedance state. When the device is brought out of shutdown, the output settles rapidly to the correct voltage level.
