What are the key features of POPA4325IPWR?

  • Zero-crossover CMOS input stage eliminates input-crossover distortion for clean rail-to-rail signal handling
  • 10 MHz gain-bandwidth product with rail-to-rail input and output swing maximizes dynamic range in low-voltage systems
  • 150 µV maximum input offset voltage enables accurate DC signal conditioning without external trimming
  • 95 dB minimum CMRR with low 10 nA bias current supports high-impedance differential sensor interfaces

What is POPA4325IPWR used for?

The POPA4325IPWR is well suited for battery-powered portable instruments, wearable sensors, and IoT edge nodes where rail-to-rail output swing and low quiescent current are critical. Its zero-crossover architecture and 10 MHz bandwidth make it ideal for precision active filter stages, ADC input buffers, and signal conditioning circuits operating from 1.8 V to 5.5 V single-supply rails. Medical diagnostic devices and industrial handheld meters also benefit from its low offset and high CMRR in compact multi-channel TSSOP-14 layouts.

Frequently Asked Questions

What does the zero-crossover feature of the POPA4325IPWR eliminate compared to a conventional CMOS rail-to-rail input op-amp?

Conventional CMOS rail-to-rail input amplifiers switch between N-channel and P-channel input pairs as the common-mode voltage crosses the midpoint, causing a discontinuous offset shift of several millivolts. The POPA4325IPWR's zero-crossover topology maintains a single consistent input pair across the full rail-to-rail common-mode range, keeping offset variation below 150 µV without discontinuities.

For a 3.3 V single-supply ADC buffer driving a 12-bit converter, how does the POPA4325IPWR's RRIO output affect usable dynamic range?

With rail-to-rail output swing to within approximately 50 mV of each supply rail, the POPA4325IPWR provides roughly 3.2 V of usable output range on a 3.3 V supply. For a 12-bit ADC with a 3.3 V reference, this utilizes over 97% of the converter's full-scale range, versus a non-RRO op-amp that may lose 0.5 V to 1 V of headroom.

How does the POPA4325IPWR's 10 MHz GBW perform in a low-pass filter application with a gain of 10 V/V?

At a closed-loop gain of 10 V/V, the POPA4325IPWR delivers approximately 1 MHz of bandwidth, suitable for filtering audio-range and low-speed sensor signals up to 500 kHz. Designers can implement second-order Sallen-Key or multiple-feedback filter stages with corner frequencies up to 200 kHz while maintaining flat passband gain.

How does POPA4325IPWR compare to OPA2325 in terms of channel count and package footprint for multi-channel designs?

The POPA4325IPWR integrates 4 op-amp channels in a TSSOP-14 package (approximately 5 mm × 4.4 mm footprint), versus the dual OPA2325 in TSSOP-8 offering 2 channels. For a 4-channel signal conditioning board, a single POPA4325IPWR reduces the package count by half and saves approximately 40 mm² of PCB area compared to two OPA2325 devices.
