Microchip MCP6N11 Instrumentation Amplifier

  • Rail-to-rail input and output operation
  • mCal on-chip calibration circuit that enables low initial offset voltage
  • Gain set by 2 external resistors
  • Hardware shutdown pin
  • Minimum gain (GMIN) options: 1, 2, 5, 10 or 100 V/V
  • 1.8V operation allows two 1.5V batteries to be drained beyond typical use
  • Common Mode Rejection Ratio (CMRR): 115 dB (typical, GMIN = 100)
  • Power Supply Rejection Ratio (PSRR): 112 dB (typical, GMIN = 100)
  • Low-power operation/shutdown requires less current for the given speed and performance
  • Extends battery life and leads to less self-heating
  • Bandwidth: 500 kHz (typical, Gain = GMIN)
  • Supply current: 800 µA/channel (typical)
  • Single channel
  • Enable/VOS Calibration pin (EN/CAL)
  • Low-power CMOS process technology
  • Power supply: 1.8V to 5.5V
  • Extended temperature range: -40°C to +125°C
