The LT6004IDD#PBF is a dual general-purpose op-amp from Linear Technology (now part of Analog Devices) with a 3 kHz gain bandwidth product and a 0.55 V/µs slew rate. That GBW tells you this part is built for DC and near-DC signal conditioning — think thermocouple amplifiers, strain-gauge bridges, photodiode current-to-voltage converters, and battery-monitor dividers — not audio or high-speed control loops. With a rail-to-rail output stage, it swings cleanly to both supply rails, which matters when running from a single 1.6 V to 16 V supply rail and you need every millivolt of headroom.
Supply current and input bias — the battery-budget view
Each amplifier draws 1.1 mA supply current, so the dual-channel total is 2.2 mA quiescent. That is low enough to leave on continuously in a battery-powered sensor node without draining the cell overnight. Input bias current is 7 pA — a FET-input level that lets you use high-impedance sensors (pH probes, pyroelectric detectors) without an extra buffer.
Package and temperature grade
Housed in an 8-WFDFN with exposed pad (8-DFN 3x3 mm), the part is surface-mount only.
