The INA333AIDGKR from Texas Instruments is a micro-power (50μA), zero-drift, rail-to-rail output instrumentation amplifier in a VSSOP-8 (DGK) package. With offset voltage of 25μV max, drift of 0.1μV/°C, and gain set by a single external resistor from 1 to 1000, it is ideal for precision measurement in battery-powered and portable applications.
