Product details

It delivers a 1.2 MHz gain-bandwidth product with a 0.4 V/µs slew rate, rail-to-rail output swing, and draws only 110 µA quiescent supply current. The supply voltage range spans 2.7 V to 36 V, making it suitable for both battery-powered 3.3 V systems and industrial 24 V rails.

Supply range and quiescent current — the design decisions

The 2.7 V minimum supply lets this part run directly from a single lithium cell or a 3.3 V rail with headroom, while the 36 V maximum covers 24 V industrial buses with margin for transients. At 110 µA supply current, the OPA170AID fits into loop-powered 4-20 mA transmitters and battery-operated instrumentation where every microamp counts. The 17 mA output drive per channel is enough to swing a 10 kΩ load rail-to-rail or drive the input of a successive-approximation ADC.

Frequently asked questions

Is OPA170AID rail-to-rail?

Yes, the OPA170AID features rail-to-rail output swing. The input common-mode range is not rail-to-rail — it extends from the negative rail to about 1.1 V below the positive rail at 3.3 V single supply.

What is the bandwidth of OPA170AID?

The gain-bandwidth product is 1.2 MHz, with a slew rate of 0.4 V/µs.

What is the equivalent of OPA170AID?

A close functional peer is the TLV9351IDCKR, which offers higher bandwidth (3.5 MHz) and faster slew rate (20 V/µs) but operates from a narrower 4.5 V minimum supply. The OPA170AID's wider 2.7 V to 36 V range and lower 110 µA quiescent current make it the better fit for low-power and wide-supply designs.
