Differential amplifier, 260 MHz, 95 V/µs — single-channel LFCSP
The ADA4940-1ACPZ-RL is a single-circuit differential amplifier from Analog Devices, designed for driving high-speed ADCs or transmitting differential signals over twisted-pair lines. Supply current is 1.25 mA typical, keeping the thermal budget in the 16-lead LFCSP package manageable even in dense multi-channel arrays.
Supply range, output drive, and temperature grade
Each output channel can source or sink 46 mA, enough to drive the sampling capacitor of a 12- to 16-bit SAR ADC without an external buffer. The output type is differential, meaning the amplifier produces a balanced pair of signals centered around a common-mode voltage — this rejects ground noise and doubles the dynamic range into a differential ADC input.
Package, reel format, and sourcing posture
The supplier device package is 16-LFCSP-VQ (3x3). Supplied on Tape & Reel (TR) or Cut Tape (CT) — the TR quantity is the standard reel count; CT is for prototype or low-volume builds. Analog Devices lists the ADA4940-1ACPZ-RL as Active in production, with ROHS3 compliance.
