(PGTIA)
FEATURES
GENERAL DESCRIPTION
► Small, dual-channel, complete PGTIA and AFE solution ► Small size package:16-lead LFCSP, 3 mm × 3 mm
► Integrated switches, 2 external gains per channel ► Wide input current dynamic range from picoamps to milliamps ► Excellent DC precision
► Low offset voltage: ±100 μV maximum, 25°C ► Low offset voltage drift: ±0.85 μV/°C maximum, −40°C to
+125°C ► Low input bias current: ±9 pA maximum, 25°C ► Low switch off leakage current : ±90 pA maximum (−40°C to
+125°C) ► New integrated architecture eliminates gain error due to switch
resistance ► Single-supply operation: +2.7 V to +5.5 V (dual-supply operation:
±1.85 V to ±2.
