VCA810IDR

Instrumentation, Op Amps, Buffer Amps Overview

The VCA810IDR is a single-channel voltage-controlled amplifier from Texas Instruments, designed for high-gain adjustment and wideband applications. It operates within a supply voltage range of 10V to 10V and functions across an extended temperature range from -40°C to +85°C. Key electrical specifications include a slew rate of 350 V/us, a common-mode rejection ratio (CMRR) of 85 dB, and an input bias current of 10 uA. The device features a low input offset voltage of 200 uV and an input voltage noise density of 2.4 nV/sqrt Hz. It is housed in an SOIC-8 surface-mount package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IDR' against the manufacturer's official datasheet to confirm the SOIC-8 package and tape-and-reel packaging configuration. Ensure that the operating conditions align with the specified 10V supply requirement and the -40°C to +85°C temperature range before integration into the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel VGA with high-speed characteristics is required. The 350 V/us slew rate supports wideband applications, while the 2.4 nV/sqrt Hz noise density suits precision signal paths. Confirm compatibility with the SOIC-8 footprint and the specific 10V dual-supply or single-supply architecture defined in the electrical characteristics.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the VCA810 series of special purpose amplifiers manufactured by Texas Instruments. It is categorized under Voltage-Gain Adjustable Amplifiers (VGA). The device is distinct from operational amplifiers like the OPA810, focusing specifically on voltage-controlled gain modulation rather than general-purpose linear amplification.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult the official TI replacement matrix for verified cross-reference part numbers. Generic VGA alternatives may not match the specific 350 V/us slew rate or 2.4 nV/sqrt Hz noise density requirements.
