Product details

Single-supply general-purpose op amp in a SOT-23-6

Input bias current is just 0.5 pA, so it can interface with high-impedance sensors without loading the source.

The 6.5 MHz gain-bandwidth product sets the small-signal bandwidth: at a closed-loop gain of 10, expect a -3 dB bandwidth around 650 kHz. The 5 V/µs slew rate determines how fast the output can swing under large-signal conditions. For a 2 V peak-to-peak output step, the full-power bandwidth is roughly 400 kHz — above that, the output will slew-rate limit and distort. If your application requires fast settling to 0.1% on a 2 V step, budget about 1 µs. The 585 µA supply current keeps the thermal rise low in the SOT-23-6 package, so you can run it near the 125°C limit without derating concerns.

Frequently asked questions

What is the difference between OPA373 and OPA374?

The OPA373 is a single-channel amplifier (1 circuit), while the OPA374 is a quad-channel version (4 circuits). If you need four amplifiers on one die, the OPA374 is the direct multi-channel sibling.

Is OPA373AIDBVT suitable for single-supply applications?

Yes, the OPA373AIDBVT is designed for single-supply operation. The input common-mode range extends from the negative rail to within about 1 V of the positive rail, so it works well for ground-referenced signals in single-supply systems.

What are alternatives to OPA373AIDBVT from other brands?

A close functional alternative is the Texas Instruments TLV9351IDCKR, a single-channel general-purpose op amp with a 3.5 MHz gain-bandwidth, 20 V/µs slew rate, and 10 pA input bias current, also in a SOT-23-6 package. Another option is the TLV9362IDDFR, a dual-channel part with 10.6 MHz GBW and 25 V/µs slew rate in an SOT-23-8 package. Both are active and ROHS3 compliant.
