TLV2465IPWR

Instrumentation, Op Amps, Buffer Amps Overview

The TLV2465IPWR is a quad low-power rail-to-rail input/output operational amplifier from Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 6 V, or split supplies of ±1.35 V to ±3 V. The device features a gain-bandwidth product of 6.4 MHz and a slew rate of 1.6 V/µs with a typical supply current of 500 µA per channel. It includes a shutdown pin that reduces current consumption to 0.3 µA per channel. Input offset voltage is typically 1 mV, and the input noise voltage density is 11 nV/√Hz at 1 kHz. It supports output currents up to 80 mA and functions within an operating temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IPWR' corresponds to the TSSOP-16 package and industrial temperature grade (-40°C to +125°C). Confirm the datasheet revision matches the required specifications, as older revisions may list different electrical limits. Ensure the ordering code aligns with the desired reel quantity and tape-and-reel packaging format.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-speed performance is required alongside low power consumption in portable devices. The quad configuration allows multiple channels in a single package, saving board space. Verify that the 6.4 MHz bandwidth meets the signal frequency requirements and that the 80 mA drive capability is sufficient for the load impedance.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLV246x family of low-power rail-to-rail operational amplifiers designed for portable applications. The family includes single, dual, quad, and hex configurations. The TLV2465 specifically provides four independent amplifiers with shutdown functionality, distinguishing it from non-shutdown variants like the TLV2464.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the function of the SHDN pin on the TLV2465?

The SHDN pin enables a micropower shutdown mode. When driven below 0.7 V, it places the amplifier outputs in a high-impedance state and reduces the supply current to approximately 0.3 µA per channel.

Does the TLV2465 support rail-to-rail operation?

Yes, the TLV2465 features both rail-to-rail input and rail-to-rail output capabilities, allowing the input common-mode voltage range to extend beyond the supply rails and the output to swing close to both supply rails.
