Product details
Frequently asked questions
What is the bandwidth of VCA821ID?
The -3 dB bandwidth is 710 MHz, with a slew rate of 2500 V/µs, defining its high-speed variable gain capability.
What is the VCA821ID equivalent or replacement?
No direct pin-compatible replacement is listed in the official records. The THS4215DRBT is a voltage-feedback amplifier with 350 MHz bandwidth and 970 V/µs slew rate, but it is not a variable gain amplifier — it serves a different function in the signal chain. For a VGA replacement, evaluate the VCA821ID's own active status first; if a second source is required, consult the factory for recommended alternatives.
Is VCA821ID available via RFQ confirmation at major distributors?
Stock levels vary across distributors. The part is available to order through independent channels; current stock and lead time are confirmed at quote time against an RFQ.
