Overview
The INA2290A5IDGKR is a dual-channel, high-side current-sense amplifier from the INAx290 family. It operates with a supply voltage of 2.7 V to 20 V and supports a common-mode input range from 2.7 V to 120 V. The device features a fixed gain of 500 V/V, a bandwidth of 800 kHz, and a slew rate of 2 V/µs. Key electrical characteristics include a maximum offset voltage of ±12 µV, a DC CMRR of 160 dB, and a quiescent current of 370 µA per channel. It is housed in an 8-pin VSSOP package.
Feature Summary
- Ultra-precise zero-drift architecture enables accurate measurement of low sense voltages across extended temperature ranges.
- High common-mode rejection ratio ensures signal integrity under varying common-mode conditions.
- Wide operating common-mode voltage range allows for flexible high-side sensing configurations.
Applications
- Active antenna system mMIMO
- Macro remote radio unit (RRU)
- 48-V rack server power supplies
Procurement Notes
Verify the specific 'A5' suffix indicates the 500 V/V gain configuration before procurement. Confirm the 'DGKR' suffix corresponds to the VSSOP-8 tape-and-reel packaging format. Ensure the component meets the required thermal and humidity sensitivity specifications for the intended manufacturing process.
Selection Notes
Select this part when a high gain of 500 V/V is required to amplify small differential signals. The dual-channel design is suitable for applications needing two independent current monitoring paths within a compact footprint. Consider the 800 kHz bandwidth limitation at this gain setting for high-speed transient detection requirements.
Part Context
This component belongs to the INAx290 series of ultra-precise current-sense amplifiers. It shares architectural similarities with the single-channel INA290 and quad-channel INA4290 but provides a dual-channel solution in a space-efficient VSSOP package. The series is characterized by its wide common-mode range and high accuracy.
