STMicroelectronics OAxZHA Operational Amplifiers

ST OA1ZHA, OA2ZHA, OA4ZHA Operational Amplifiers

STMicroelectronics OA1ZHA, OA2ZHA, OA4ZHA low power, high precision op amps, offer very low input offset voltages with virtually zero drift. OA1ZHA, OA2ZHA, OA4ZHA are respectively the single, dual and quad operational amplifier versions, with pinout compatible with industry standards. The OA1ZHA, OA2ZHA, OA4ZHA series offers rail-to-rail input and output, excellent speed/power consumption ratio, and 400kHz gain bandwidth product, while consuming less than 40µA at 5V. All devices also feature an ultra-low input bias current. The OA1ZHA, OA2ZHA, OA4ZHA family is the ideal choice for wearable, fitness and healthcare applications.

  • Very high accuracy and stability: offset voltage 5µV max at 25°C, 8µV over full temperature range (-40°C to 125°C)
  • Rail-to-rail input and output
  • Low supply voltage: 1.8 - 5.5V
  • Low power consumption: 40µA max. at 5V
  • Gain bandwidth product: 400kHz
  • High tolerance to ESD: 4kV HBM
  • Extended temperature range: -40 to +125°C
  • Micro-packages: SC70-5, DFN8 2x2, and QFN16 3x3
  • High precision op amp without the need of calibration
  • Accuracy virtually unaffected by temperature change

  • Wearable
  • Fitness and healthcare
  • Medical instrumentation
