INA199B3DCKR

The INA199B3DCKR is a Texas Instruments high-side current-sense monitor in an 8-pin DCK package. It amplifies the voltage drop across a shunt resistor to produce a proportional, analog output voltage that reflects load current, suitable for monitoring with high common-mode voltages. The device uses a REF pin to set the output baseline (zero current), has no digital interface (purely analog), and is designed for automotive/industrial power-management use with low offset and fast response. The “B3” suffix indicates a specific grade/variant, and “DCKR” denotes the package type and reel option. It is ideal for applications requiring simple current measurement across a wide common-mode range, compact packaging, and ease of integration. For exact electrical specs (supply range, shunt voltage range, gain, output swing, TA, pinout), refer to the INA199B3DCKR datasheet.

Note: For exact electrical specifications (V+, Vsense range, Iout scale, etc.), please refer to the datasheet for this specific lot/date code.

- Pin count: 8 pins
- Function: High-side current-sense monitor (current-sense amplifier). It senses the voltage across a shunt via IN+ and IN− and outputs a voltage on OUT proportional to the sensed current. REF provides an offset for the output. Powered from V+ with GND. The B3DCKR suffix indicates an 8-pin VSSOP (DCK) package, reel version.

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits and embedded processing devices for various industries.
