VCA824ID

Instrumentation, Op Amps, Buffer Amps Overview

The VCA824ID is an ultra-wideband variable gain amplifier from Texas Instruments, housed in a 14-pin SOIC package. It features a gain adjustment range exceeding 40 dB with linear control in V/V. The device operates on dual supplies ranging from 7 V to 12 V and supports a bandwidth of 320 MHz. Key electrical parameters include a slew rate of 2.5 kV/us, an input bias current of 25 uA, and an input offset voltage of 17 mV. It functions within a temperature range of -40 C to +85 C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Offers flexible gain control with a linear response in V/V mode.
• Features high slew rate performance to minimize harmonic distortion.

Instrumentation, Op Amps, Buffer Amps Applications

• Differential line receivers
• Signal equalizers
• Pulse shaping circuits
• Automatic gain control (AGC) systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix ID indicates the SOIC-14 package variant. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure supply voltage requirements match the 7 V to 12 V operational range specified in the datasheet.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a linear-in-V/V gain control characteristic is required. Compare against the VCA821 if a linear-in-dB control scheme is preferred instead. Consider the 320 MHz bandwidth and 2.5 kV/us slew rate for high-frequency applications requiring low distortion.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the VCA82x series of wideband variable gain amplifiers. It shares architectural similarities with the VCA820, VCA821, and VCA822 but offers distinct control linearity options. The series is designed for professional video, test measurement, and communication markets.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The VCA824IDG4 is a lead-free version of the same functional device. Verify pinout compatibility when substituting with other members of the VCA82x family.
