Product Details
INA199A2DCKR – TI 26V Bidirectional Zero-Drift Current-Sense Amplifier
INA199A2DCKR is a Texas Instruments voltage-output current-shunt monitor for precise low-side and high-side current measurement. With a -0.3V to 26V common-mode range, 100V/V fixed gain, zero-drift architecture and compact 6-pin SC70 package, it is suitable for power monitoring, battery chargers, telecom equipment, portable systems and overcurrent protection.
Engineering note: Verify the latest TI datasheet, shunt resistor value, REF pin bias, common-mode range, output swing and PCB layout before production approval.
Component Overview
INA199A2DCKR belongs to the TI INA199 family of zero-drift, voltage-output current-shunt monitors. It measures the small voltage drop across a current-sense resistor and outputs an amplified voltage for an ADC, MCU, comparator or feedback control circuit.
Circuit Function & Design Role
Supports current measurement in both directions when the REF pin is biased correctly, useful for charge and discharge current monitoring.
Measures current on the supply side while keeping the load referenced to system ground.
Can be used near ground for load-current measurement, current feedback and protection circuits.
The A2 gain option provides higher output scaling than A1, useful when the shunt voltage is small.

TomatoElec Quality & Supply Notes
As an in-stock independent distributor and electronic components supplier, TomatoElec supports INA199A2DCKR sourcing for engineering samples, production replenishment, urgent replacement and BOM purchasing. For current-sense amplifiers, correct gain option, package type and original sourcing are important because the device affects measurement accuracy and protection behavior.
- Original component sourcing: support sourcing of original Texas Instruments current-sense amplifier ICs for customer BOM requirements.
- Inventory support: help customers confirm available stock, package condition, date code and shipment schedule.
- Gain option verification: confirm the A2 100V/V gain option before shipment, especially when comparing with INA199A1 or INA199A3 versions.
- BOM matching: verify gain, common-mode range, supply voltage, package, REF pin usage and temperature requirements before approving any substitute.
Replacement & BOM Matching Guidance
INA199A2DCKR should not be replaced only by matching the current-sense amplifier category. Engineers should compare gain, zero-drift architecture, common-mode range, offset voltage, REF pin configuration, package, pinout and operating temperature range.
