Zero-drift amplifier in a 3×3 DFN — what you get
The LTC2057IDD#TRPBF is a single-channel zero-drift operational amplifier from Analog Devices. It delivers a 0.5 µV typical input offset voltage and a 1.5 MHz gain-bandwidth product, with a 0.45 V/µs slew rate. The output swings rail-to-rail, and the supply range spans 4.75 V to 36 V, making it a fit for precision DC measurement, current sensing, and bridge-amplifier circuits in industrial control, instrumentation, and test equipment.
0.5 µV offset — the so-what for your BOM
A 0.5 µV input offset means this part can resolve microvolt-level signals without external trimming or auto-zero cycles. That 900 µA supply current is the trade-off — it draws more than a chopper-stabilized amp at lower bandwidth, but the wide 36 V supply headroom keeps it useful on unregulated industrial rails. The 30 pA input bias current is low enough for high-impedance sensor interfaces like thermocouples or strain gauges.
Package and thermal pad — layout note
The pad is the only thermal path — without it, junction temperature rises quickly above 85°C ambient. Surface-mount only; no socket option for field swap.
Active lifecycle — no LTB worry
It remains a current-production choice for new designs.
