OPA890IDBVT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA890IDBVT is a single-channel, low-power, wideband voltage feedback operational amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 12 V and consumes only 1.1 mA of quiescent current per channel. The device features a gain-bandwidth product of 130 MHz and a high slew rate of 500 V/µs. Key electrical specifications include an input offset voltage of 1 mV, an input bias current of 2 µA, and an output short-circuit current capability of 40 mA. It provides a voltage gain of 62 dB and a common-mode rejection ratio of 67 dB. The component is housed in a compact SOT-23-6 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix (DBVT) confirms the SOT-23-6 package and tape-and-reel delivery format. Confirm that the device includes the integrated disable feature if power-down functionality is required for the design. Ensure the manufacturer is identified as Texas Instruments or its authorized predecessor entities to guarantee authenticity and datasheet alignment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance of moderate bandwidth and ultra-low power consumption is critical. It is suitable for applications where space is constrained by the SOT-23-6 footprint. Consider alternatives if higher precision, lower noise, or rail-to-rail input/output characteristics are mandatory for the specific circuit topology.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPA890 series of wideband operational amplifiers designed for efficiency. It complements other high-speed op-amps by offering a disable pin, which distinguishes it from standard non-disabling variants. The family targets applications needing fast transient response without excessive static power draw.
