DATASHEET ISL28133 FN6560 Rev.7.00 Single Micropower, Chopper Stabilized, RRIO Operational Amplifier Sep 26, 2015 The ISL28133 is a single micropower, chopper stabilized Features operational amplifier that is optimized for single supply Low input offset voltage 8V, Max. operation from 1.8V to 5.5V. Its low supply current of 18A and wide input range enable make it an excellent general Low offset TC 0.075V/C, Max purpose op amp for a range of applications. The ISL28133 is Input bias current 300pA, Max. ideal for handheld devices that operate off 2 AA or single Li-ion Quiescent current .18A, Typ. batteries. Wide supply range . 1.8V to 5.5V The ISL28133 is available in the 5 Ld SOT-23, the 5 Ld SC70, and the 6 Ld 1.6mmx1.6mm TDFN packages. All devices operate Low noise (0.01Hz to 10Hz) 1.1V , Typ. P-P over the extended temperature range of -40C to +125C. Rail-to-rail inputs and output Operating temperature range -40C to +125C Related Literature AN1480 ISL28133ISENSEV1Z Evaluation Board Users Applications Guide Bidirectional current sense AN1499 ISL28133EVAL1Z High-Gain Evaluation Board Temperature measurement Users Guide Medical equipment Electronic weigh scales 10 V S I-SENSE+ N = 67 1.8V TO +5.5V 8 MAX V 6 REF 4 499k 4.99k 3 5 MEDIAN + V+ 2 1 ISL28133 V SENSE 4 V- 0 OUT 0.1 - 2 499k -2 4.99k MIN -4 -6 -40 -20 0 20406080 100 120 GND TEMPERATURE (C) I-SENSE- BIDIRECTIONAL CURRENT SENSE AMPLIFIER FIGURE 2.
