MCP62x and MCP65x Op Amps with mCal

Microchip's operational amplifiers with an on-chip, digital calibration circuit (mCal Technology)

MCP62x and MCP65x, Op Amps with mCal The MCP62x and MCP65x families of 20 MHz and 50 MHz operational amplifiers are fabricated using Microchip Technology's low power CMOS technology. In addition to the mCal technology, which minimizes input offset voltage, these two families of amplifiers offer high output drive and rail-to-rail output swing.

mCal is an on-board calibration circuit that corrects the input offset error of the amplifier. This circuitry consists of an A/D converter, a reference, and an output DAC that feeds an offset correction factor back into the amplifier. This calibration occurs during power-up or is based on the state of the calibration pin. This calibration circuitry enables low initial offset voltage and a way to minimize drift over time and temperature.

Features
  • Operating voltage from 2.5 V to 5.5 V
  • GBWP of 20 MHz / 50 MHz, typical
  • Available in single and dual; featuring chip select and mCal technology
  • Rail-to-rail output
    • Greater dynamic range, even at lower operating voltages
    • Better performance across entire operating voltage range
  • High output drive: 85 mA / 95 mA, (typ.)
    • Capable of driving heavy loads
    • Better performance across a wide range of applications
  • Extended temperature range
    • -40°C to +125°C
Benefits
  • The mCal feature provides low initial voltage offset upon power-up. In addition, the CAL pin allows the user to re-calibrate the device at any time, thereby reducing offset drift over time and temperature.
  • High output drive and rail-to-rail output swing provides exceptional performance for the most demanding applications that require driving heavy loads.
  • Rail-to-rail output operation provides for greater dynamic range. This is especially critical at lower operating voltages where the signal voltage swing is relatively small.
  • Low initial offset and low drift over time and temperature (via CAL pin)
  • Capable of driving heavy loads
  • Greater dynamic range, even at lower operating voltages
