0.5 µV offset, zero-drift — why this amp exists
The ADA4523-1BCPZ is a single-channel zero-drift operational amplifier from Analog Devices that targets precision DC and low-frequency signal chains where offset drift and 1/f noise ruin the measurement. Its 0.5 µV typical input offset and zero-drift topology mean the offset stays flat over temperature and time — no external nulling trim needed. The 5 MHz gain-bandwidth product and 1.8 V/µs slew rate cover sensor conditioning, ADC drivers, and active filters up to a few hundred kilohertz without burning excessive supply current (4.5 mA typical).

Sourcing and lifecycle note
The series code ADA4523 is printed on the top mark — verify the date-code laser etch matches the manufacturer's plant font for that week if you are buying from a non-franchised channel.
