Overview

The μPC844 and μPC4744 are high-speed versions of the single-power general-purpose operational amplifier, μPC451, μPC324, realizing high-speed response and high stability. By adopting a High-Speed PNP transistor circuit, various characteristics such as slew rate and gain bandwidth are improved, as compared to μPC451 and μPC324, the load capacity stability is also improved, with no crossover distortion. It can be used widely for various application circuits such as single power supply AC amplifiers, active filters, line drivers, amplifiers for light receiving elements, etc. Depending on the usage and operating ambient temperature range, the μPC844 is designed for extended temperature and suited for wide operating ambient temperature applications, and μPC4744 is designed for general purposes. Along with this series of lineup, the dual type operational amplifier, µPC842, μPC4742 with the same circuit configuration are also available.

  • Slew Rate (AV = 1 ): 7V/µs (TYP.) (V+ = +5V, V- = GND)
  • Gain Bandwidth Product (f = 100kHz): 3.5MHz (TYP.)
  • Input Offset Voltage: ±2mV (TYP.)
  • Input Offset Current: ±6nA (TYP.)
  • Operating Ambient Temperature μPC844G2 : TA = -40 °C ~ +85 °C, μPC4744G2 : TA = -20 °C ~ +80 °C, μPC844GR-9LG : TA = -40 °C ~ +125 °C, μPC4744GR-9LG : TA = -40 °C ~ +85 °C,
  • Stability to capacitive load (Capacitive load, 1000pF)
  • Built-in phase correction circuit.
  • Built-in output short-circuit protection circuit.
  • Standard pin (pin compatible) configuration of a quad operational amplifier.
