Texas Instruments  PINA333QDGKRQ1

The INA333-Q1 is alow-power, precision instrumentation amplifier offering excellent accuracy. The versatilethree-operational-amplifier design, small size, and low power make this device an excellent choicefor a wide range of automotiveapplications that use resistive bridge sensors.

A single external resistor sets any gain from 1 to 1000. The INA333-Q1 is designed to use anindustry-standard gain equation: G = 1 + (100 kΩ /RG).

The INA333-Q1 providesvery low offset voltage (25 µV, G ≥ 100), excellent offset voltage drift
(0.1 µV/°C, G ≥ 100), and high common-mode rejection (100 dB at G ≥ 10). The device operateswith power supplies as low as 1.8 V (±0.9 V) and quiescent current is only 50 µA, making thisdevice an excellent choice for battery-operated systems. Autocalibration techniques maintainexcellent precision over the industrial temperature range. The INA333-Q1 also offers exceptionally lownoise density (50 nV/√Hz) that extends down to dc.

The INA333-Q1 device isavailable in an 8-pin VSSOPpackage and isspecified over the TA = –40°C to +125°C temperature range.
