Product details

What this op-amp brings to the signal chain

The Texas Instruments OPA350UA is a single-channel general-purpose op-amp from the MicroAmplifier™ family, packing a 38 MHz gain-bandwidth product and a 22 V/µs slew rate into an 8-SOIC package. Rail-to-rail output lets it swing close to the supply rails on a 2.5 V to 5.5 V span, which matters when you are driving an ADC or a low-voltage signal path without a separate rail splitter. Input bias current sits at 0.5 pA — low enough for high-impedance sources like photodiodes or pH probes. The -40°C to 85°C temperature range covers industrial control and outdoor telecom cabinets.

38 MHz GBW and 22 V/µs slew rate — what they mean for your design

A 38 MHz gain-bandwidth product and 22 V/µs slew rate support fast ADC front-ends and active anti-aliasing filters.

Sourcing posture

We source the OPA350UA through independent distribution and franchised-excess channels. Send an RFQ for quantity and lead time.

Frequently asked questions

Where can I buy OPA350UA?

We source the OPA350UA to order against an RFQ through independent and franchised-excess channels. Send a quote request with your target quantity and we will confirm availability and pricing.

What is the OPA350UA equivalent or closest second-source?

The TLV9351IDCKR is a functional peer from TI — single rail-to-rail op-amp in a similar bandwidth class (about 3.5 MHz GBW, 20 V/µs slew rate). It is not pin-for-pin identical (different package), but it can serve as a drop-in alternate on a redesigned PCB for supply resilience.

What is the OPA350UA pin configuration?

The OPA350UA uses the standard 8-SOIC pinout for a single op-amp: offset null (pins 1 and 5), inverting input (pin 2), non-inverting input (pin 3), V- (pin 4), output (pin 6), V+ (pin 7), and NC (pin 8). The datasheet provides the full diagram.

OPA350UA vs OPA2350 – what's the difference?

The OPA350UA is a single-channel op-amp; the OPA2350 is the dual-channel version in a different package. Both share the same 38 MHz GBW, 22 V/µs slew rate, and rail-to-rail output. Choose the OPA350UA for single-channel designs and the OPA2350 when you need two amplifiers on one die.
