OPA2317QDGKRQ1 zero-drift operational amplifier
The OPA2317QDGKRQ1 from TI is an AEC-Q100 qualified, dual-channel, zero-drift operational amplifier designed for high-precision signal conditioning in automotive and industrial systems. Housed in a compact 8-pin VSSOP package, this CMOS op-amp operates over a wide supply range of 1.8V to 5.5V and delivers rail-to-rail input and output (RRIO) performance, maximizing dynamic range in low-voltage applications. It leverages proprietary auto-calibration technology to achieve an ultra-low offset voltage of 20µV (typ) and near-zero drift over time and temperature (0.05µV/°C typ), ensuring long-term stability. With a 300kHz gain bandwidth and a quiescent current of just 21µA per channel, it offers an optimal balance of precision and power efficiency for battery-operated devices.
OPA2317QDGKRQ1 Rail-to-Rail Op Amp Applications
● Automotive Sensing: High-side and low-side current shunt monitoring in EV/HEV battery management systems (BMS), motor drives, and powertrain controllers.
● Sensor Signal Conditioning: Amplification and filtering of signals from thermistors, pressure sensors, and position sensors in ADAS and body control modules.
● Portable Medical Devices: ECG front-ends, blood glucose meters, and portable monitors where low power and high DC accuracy are critical.
● Industrial Control: Precision bridge transducer amplification for load cells and strain gauges in PLC analog input modules.
Alternative Models
1. OPA2317IDGKT: Industrial-grade version of the same dual zero-drift op-amp, suitable for non-automotive applications with a 0°C to +70°C range.
2. MAX44267AUD+T (Analog Devices): A dual, zero-drift, RRIO op-amp with similar 1.8V to 5.5V operation and 20µV offset, offered in a TSSOP-8 package.
3. ADA4522-2ARMZ-R7 (Analog Devices): A dual-channel, zero-drift amplifier with wider 2.2MHz bandwidth and 0.3µV offset, ideal for higher-speed precision applications.
4. LMP2022MF/NOPB (Texas Instruments): A dual precision op-amp with 3MHz GBW and 4µV offset, providing an alternative balance of speed and accuracy.
