Description
General part information
INA333-HT Series
The INA333-Q1 is a low-power, precision instrumentation amplifier offering excellent accuracy. The three-op-amp design, small size, and low power make this device an excellent choice for automotive applications that require precise measurements, such as current leakage detection. This INA333-Q1 is also a great choice for applications that use resistive bridge sensors.
A single external resistor sets any gain from 1 to 1000. The INA333-Q1 is designed to use an industry-standard gain equation: G = 1 + (100 kΩ / R G).
The INA333-Q1 provides very low offset voltage (25 µV, G ≥ 100), excellent offset voltage drift (0.1 µV/°C, G ≥ 100), and high common-mode rejection (96 dB at G ≥ 10). The device operates with power supplies as low as 1.8 V (±0.9 V), and quiescent current is only 50 µA. Auto-calibration techniques maintain excellent precision over the automotive temperature range. The INA333-Q1 provides a very low peak-to-peak noise of 1 µV.
