Frequently Asked Questions
What is the supply voltage range and CMRR specification of the LT1990AIS8#PBF difference amplifier?
The LT1990AIS8#PBF operates from a supply of ±18 V (36 V total single-supply equivalent) and achieves a common-mode rejection ratio of 75 dB typical and 70 dB minimum. This high CMRR ensures that differential signals as small as a few millivolts are accurately amplified even when riding on a large common-mode voltage near the supply rails.
For automotive current sensing on a 24 V bus, how does the LT1990AIS8 handle high common-mode voltages?
The LT1990AIS8#PBF is designed to reject common-mode voltages up to ±18 V while amplifying small differential signals, making it directly usable on 12 V or 24 V automotive battery buses without an external attenuator. With a rail-to-rail output and AEC-Q100 Grade qualification, it maintains accurate current measurement from -40°C to 125°C across automotive operating conditions.
When is the LT1990AIS8#PBF a more compact solution than a discrete instrumentation amplifier for differential sensing?
The LT1990AIS8#PBF integrates precision resistor matching and frequency compensation in a single 8-pin SOIC package, eliminating the 3-op-amp topology and 8+ discrete components required for a full instrumentation amplifier design. This reduces PCB area by over 60%, simplifies calibration, and ensures that the 75 dB CMRR is maintained without resistor trimming, making it preferable for cost-sensitive automotive and industrial sensor modules.
