Overview
The INA212BIDCKR is a single-channel current sense amplifier from Texas Instruments' Zero-Drift series, housed in an SC-70-6 surface-mount package. It operates on a supply voltage ranging from 2.7 V to 26 V with a typical supply current of 65 µA. Key electrical specifications include a gain-bandwidth product of 14 kHz, a slew rate of 0.4 V/µs, and an input bias current of 28 µA. The device features a maximum input offset voltage of 0.55 µV and supports an operating temperature range from -40°C to 125°C.
Feature Summary
- Zero-drift architecture minimizes offset voltage drift over temperature and time
- Supports high-side and low-side current sensing applications
- Single-ended output configuration for simplified interfacing
Applications
- Battery management systems
- Power supply monitoring
- Industrial process control
Procurement Notes
Verify the specific suffix 'CKR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the bidirectional or unidirectional variant matches the application's current flow requirements, as the base part number may encompass multiple configurations. Ensure the SC-70-6 footprint aligns with the PCB design constraints.
Selection Notes
Select this component when ultra-low offset voltage and minimal drift are critical for measurement accuracy in space-constrained designs. The low supply current makes it suitable for battery-powered devices. Compare against other members of the INA21x family if higher bandwidth or different gain options are needed, while ensuring the thermal performance meets the system's junction temperature limits.
Part Context
This device belongs to the INA210-INA215 family of precision current sense amplifiers. These parts share common characteristics such as zero-drift technology and wide supply voltage ranges. The INA212 specifically offers a 14 kHz bandwidth, distinguishing it from lower-speed variants like the INA210 or higher-speed models like the INA214 within the same product line.
Replacement Considerations
Direct substitutes within the same package and pinout include other variants from the INA21x series, such as INA210BIDCKR or INA213BIDCKR, provided their specific bandwidth and gain specifications meet the circuit requirements.
