Frequently Asked Questions
What is the gain of the INA199B2RSWR?
The INA199B2RSWR uses a fixed-gain voltage-feedback architecture. The 'B2' designation in the part number indicates a specific gain setting. Texas Instruments offers the INA199 series in multiple gain options (A1/A2/A3, B1/B2/B3, C1/C2/C3), so check the datasheet for the exact gain value of the B2 variant, typically in the range of 50V/V to 200V/V.
What is the common-mode rejection ratio (CMRR) of the INA199B2RSWR?
The INA199B2RSWR features a minimum CMRR of 100dB and a nominal CMRR of 120dB. This high rejection ratio ensures accurate current measurements even in the presence of large common-mode voltages, making it suitable for high-side and low-side current sensing in noisy industrial and automotive environments.
What applications is the INA199B2RSWR best suited for?
The INA199B2RSWR excels in battery management systems, motor drive current monitoring, power supply load sensing, and solar/renewable energy systems. Its 150µV max input offset voltage and high CMRR enable accurate current measurement in precision power monitoring equipment, industrial automation, and portable devices where low power consumption and small footprint are required.
Can the INA199B2RSWR replace other current sense amplifiers?
The INA199B2RSWR can replace similar fixed-gain current shunt amplifiers such as the INA180, INA181, or MAX4080 in many designs. Verify pin compatibility, supply voltage range, gain value, and bandwidth before substitution. The UQFN-10 package footprint should also match your PCB layout. Always consult the INA199 datasheet for full electrical specifications before making a direct replacement.
What is the package type and pin count of the INA199B2RSWR?
The INA199B2RSWR comes in a UQFN-10 package (Ultra-thin Quad Flat No-Lead, 10 pins), also identified by JESD-30 code R-PQCC-N10. This compact surface-mount package measures just a few millimeters on each side, making it well-suited for high-density PCB designs in portable electronics, wearables, and space-constrained industrial modules.
