MCP6S26-I/P

Overview

The MCP6S26-I/P is a six-channel programmable gain amplifier (PGA) in a 14-pin PDIP package. It features an SPI interface for selecting gains of +1, +2, +4, +5, +8, +10, +16, or +32 V/V. Key electrical parameters include a maximum input offset voltage of ±275 µV, a typical bandwidth of 2 to 12 MHz, and a supply voltage range of 2.5V to 5.5V. The device supports rail-to-rail input and output operation with a shutdown mode for power conservation.

Feature Summary

• Six analog inputs selectable via serial peripheral interface
• Rail-to-rail input and output capability
• Configurable gain settings from +1 V/V to +32 V/V
• Shutdown mode for reduced power consumption

Applications

• A/D converter driver circuits
• Multiplexed analog signal processing
• Data acquisition systems
• Industrial instrumentation
• Medical instrumentation

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +85°C) and '/P' denotes the PDIP package. Confirm datasheet revision DS21117B matches current manufacturing specifications. Ensure compatibility with system SPI logic levels and single-supply voltage requirements between 2.5V and 5.5V before integration.

Selection Notes

Select this component when six independent analog channels require programmable amplification within a single integrated circuit. It is suitable for applications needing low offset voltage and high bandwidth. Consider the PDIP-14 package constraints for through-hole mounting. Verify that the required gain steps align with the available eight discrete options provided by the internal resistor ladder.

Part Context

This part belongs to the MCP6S21/2/6/8 family of single-ended, rail-to-rail PGAs. While sharing core architecture with the one-channel MCP6S21, two-channel MCP6S22, and eight-channel MCP6S28, the MCP6S26 specifically provides six multiplexed inputs. All variants utilize the same SPI control logic and operate over the specified temperature range.
