The ADA4896-2/ADA4897-1/ADA4897-2 is a low noise, low power, single supply range amplifier with 2.4nV/√Hz of low 1/f noise and 3mA of static current.
The ADA4896-2, ADA4897-1 and ADA4897-2 are unity‑gain stable, low‑noise, rail‑to‑rail output voltage‑feedback amplifiers. They operate from a wide supply range of 3 V to 10 V and draw only about 3 mA per amplifier, making them suitable for power‑constrained designs.
Key performance figures include a –3 dB bandwidth of 230 MHz, a slew rate of 120 V/ps, input voltage noise of 24 nV/√Hz at 10 Hz, and an input offset voltage of 0.5 mV maximum. The devices are offered in multiple package options (8‑lead LFCSP, MSOP, SOIC, and 6‑lead SOT‑23) and are rated for an industrial temperature range of –40 °C to +125 °C.
