1 µV offset eliminates the trim pot
The AD8574ARUZ-REEL: Gain-bandwidth product is 1.5 MHz with a slew rate of 0.4 V/µs, which suits DC-accurate sensor conditioning and low-frequency signal chains up to a few tens of kHz; for a 10 kHz sine output at 2 Vpp, the slew rate margin is adequate. Supply current is 850 µA total for all four amplifiers — each channel draws roughly 212 µA, making this a low-power choice for multi-channel data-acquisition systems running on a 2.7 V to 5 V rail.
Industrial temperature and package fit
Rated for -40°C to 125°C operation, the AD8574ARUZ-REEL covers the full industrial temperature band — suitable for outdoor telecom cabinets, engine-bay electronics, or factory-floor sensor modules where ambient heat is a given. Housed in a 14-lead TSSOP package (0.173" wide, 4.40 mm body), the footprint is compact enough for dense mixed-signal boards. The rail-to-rail output stage swings within 50 mV of each supply rail, preserving headroom in low-voltage 2.7 V systems. Output can source or sink 30 mA per channel — enough to drive a 2.5 V reference into a 10-bit ADC or a small analog meter, but not intended for heavy loads like relays or solenoids.
Sourcing and lifecycle — no LTB pressure
The input bias current is 1 nA typical, which is higher than the picoamp-level bias of some chopper-stabilized competitors — something to verify if the source impedance exceeds 100 kΩ, where the bias current times impedance starts to rival the 1 µV offset.
