What are the key features of POPA4388IDR?

  • Zero-drift architecture with 7.5 µV maximum input offset voltage and near-zero drift over temperature for precision DC measurements without periodic calibration
  • 10 MHz gain-bandwidth product with zero-crossover true RRIO design eliminating phase reversal artifacts at input common-mode limits
  • 134 dB typical common-mode rejection ratio (CMRR) with 114 dB minimum, ensuring high noise immunity in differential signal acquisition circuits
  • 0.7 nA maximum bias current enabling accurate operation with high-impedance sources such as photodiodes and pH sensors without significant input loading

What is POPA4388IDR used for?

The POPA4388IDR is designed for precision instrumentation applications including load cell amplifiers, thermocouple signal conditioning, and 4-20 mA current loop transmitters where sub-10 µV offset and long-term drift stability are required. Its zero-crossover RRIO architecture makes it ideal for single-supply differential amplifier stages in data acquisition front-ends that must process signals spanning the full supply range without gain discontinuity. Medical measurement equipment, precision weighing scales, and industrial sensors operating from 2.7 V to 5.5 V single-supply rails also benefit from the combination of 10 MHz bandwidth and extremely low 0.7 nA bias current.

Frequently Asked Questions

What input offset voltage does the POPA4388IDR guarantee, and how does zero-drift help long-term precision?

The POPA4388IDR guarantees a maximum input offset voltage of 7.5 µV at room temperature, maintained across the full operating temperature range thanks to its zero-drift auto-correction architecture. Zero-drift continuously corrects offset and drift internally, so signal conditioning circuits such as load cell amplifiers maintain accuracy without periodic system-level calibration over months or years of operation.

How does zero-crossover RRIO benefit amplifier circuits near the supply rails?

A conventional RRIO op-amp switches between PMOS and NMOS input differential pairs as the common-mode voltage crosses mid-supply, causing a brief gain and offset discontinuity. POPA4388IDR eliminates this crossover artifact entirely, so the 10 MHz bandwidth and 7.5 µV offset remain consistent across the full 0 V to VCC input range, which is critical in single-supply ADC driver circuits operating from 3.3 V or 5 V rails.

For a photodiode transimpedance amplifier, why does POPA4388IDR's 0.7 nA bias current matter?

In a transimpedance amplifier with a 10 MΩ feedback resistor, a 0.7 nA bias current produces only 7 mV of output offset error, compared to 70 mV from a 7 nA bias current amplifier. This 10x reduction allows POPA4388IDR to accurately amplify photodiode currents as small as 1 nA to 10 nA without the output being dominated by bias current error, making it suitable for optical glucose meters and low-light spectroscopy instruments.

When would designers select POPA4388IDR over a standard precision op-amp for a 4-20 mA current loop transmitter?

A 4-20 mA transmitter spanning 0 to 100°C ambient requires an op-amp whose offset drift stays below 1 µV/°C to maintain 16-bit linearity. POPA4388IDR's zero-drift design holds total error under 0.5 µV/°C typical, versus 5 µV/°C to 15 µV/°C for standard CMOS precision amplifiers. Over a 80°C temperature excursion, this reduces drift-induced error by more than 10x, enabling accurate 4-20 mA loop measurements without temperature compensation in industrial field transmitters.
