The AD8330ACPZ-R2 is a single-channel variable gain amplifier (VGA) from Analog Devices. Its 150 MHz -3 dB bandwidth defines the useful frequency range before gain rolls off by 3 dB — for a 10 MHz carrier, the amplifier has headroom; for a 100 MHz signal, the gain flatness across the passband depends on the external gain-setting network. In a pulse application with a 5 V step, the output rises in about 3.3 ns — fast enough for most IF and baseband paths up to the bandwidth limit.
Supply, output, and temperature — the board-level decisions
Output is differential and rail-to-rail — it swings to within a few mV of each supply rail. This drives the inputs of differential ADCs directly or feeds a balun for single-ended conversion. The 100 nA input bias current is bipolar-stage typical; with a 10 kΩ source impedance the offset error is 1 mV, negligible for most gain-controlled paths, but at 100 kΩ it becomes 10 mV and may need a DC servo.
Package and tape-and-reel — what arrives on the reel
Ordered as Tape & Reel (TR) for pick-and-place or Cut Tape (CT) for bench prototypes. The TR suffix on the order code signals reel quantity; the CT variant is the same die and package, just different packaging for the distribution channel.
Production status and compliance — sourcing reality
ROHS3 compliant, so no exemption-based conflict with EU RoHS directives.
