14-SOIC (0.154", 3.90 mm width). Supply current 34 mA, output 90 mA per channel. Supply span 7 V to 12 V. Surface mount, Tube.
Active product status and ROHS3 compliant. No end-of-life notice or last-time-buy schedule. Sourced to order against RFQ; availability and pricing confirmed at quote time.
The -3 dB bandwidth is 710 MHz, with a slew rate of 2500 V/µs, defining its high-speed variable gain capability.
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.
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.
