Key Features
- AEC-Q100 automotive qualification ensures reliability in -40°C to 125°C underhood environments
- 103 dB typical common-mode rejection ratio for superior noise immunity in automotive sensor front-ends
- Dual-channel configuration in an 8-pin SOIC saves board space versus two single op-amp packages
- Voltage-feedback architecture with internal frequency compensation simplifies stable amplifier design
Applications
The TSV912AQDGKRQ1 is designed for automotive sensor signal conditioning circuits such as current-sense amplifiers in battery management systems, differential pressure sensor interfaces, and position sensor signal chains operating across the -40°C to 125°C automotive temperature range. Its high CMRR of 103 dB suppresses ground noise and EMI interference common in automotive wiring harnesses, making it suitable for safety-relevant control modules. The dual-channel package also fits non-automotive precision instrumentation and industrial measurement applications where two matched amplifiers are needed in a compact 8-pin footprint.

Frequently Asked Questions
What is the CMRR of the TSV912AQDGKRQ1, and why does it matter for automotive sensor interfaces?
The device provides a typical common-mode rejection ratio of 103 dB, with a minimum of 57 dB. In a 12 V automotive system where ground plane noise can reach 100 mV, 103 dB CMRR attenuates that noise to below 0.7 µV at the differential output, preventing measurement errors in a current-sense or pressure-sensor front-end that requires 1 mV accuracy.
What temperature range does the TSV912AQDGKRQ1 cover, and is it suitable for engine-bay use?
The TSV912AQDGKRQ1 is AEC-Q100 qualified for the full automotive temperature range of -40°C to 125°C, meeting Grade 1 requirements for underhood placement. At 125°C the maximum input offset voltage remains specified at 1500 µV, which is well within the 5 mV accuracy budget of most throttle-position and exhaust-gas temperature sensor interfaces located near the engine block.
How does the dual-channel configuration of TSV912AQDGKRQ1 benefit an automotive differential signal conditioning board?
Packing 2 op-amp channels into a single 8-pin SOIC reduces the PCB area for a differential pair front-end from about 60 mm² (two SOT-23-5 singles) to roughly 30 mm², and ensures both amplifiers share the same die for closely matched offset and gain drift. In a Hall-effect current sensor circuit this matching keeps differential gain error below 0.1% across the -40°C to 125°C range without trimming.
When should a designer choose TSV912AQDGKRQ1 over a standard commercial op-amp for an in-vehicle application?
Whenever the design must pass automotive EMC and reliability standards such as AEC-Q100 Grade 1 or ISO 11452, TSV912AQDGKRQ1 is the correct choice because it has been stress-tested to those exact qualification levels. Standard commercial op-amps rated only to 85°C ambient would fail long-term in an underhood environment where peak temperatures reach 125°C, leading to field failures and warranty costs far exceeding the small price premium of the automotive-grade device.
