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.

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.

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.

INA199A2DCKR is a compact zero-drift current-sense amplifier for designs requiring bidirectional current measurement, 100V/V gain and a small SC70-6 package. Its main value is in battery charging, power management, telecom equipment, overcurrent protection and precision current monitoring.
