16 / 43 page  8 Detailed Description 8.1 Overview The INA296x is a high-side, inline, or low-side bidirectional, high-speed current-sense amplifier that offers a wide common-mode range, precision zero-drift topology, excellent common-mode rejection ratio (CMRR) and fast slew rate. Different gain versions are available to optimize the output dynamic range based on the application. The INA296x is designed using an architecture that enables low bias currents of 35 µA with a specified common-mode voltage range from –5 V to 110 V with signal bandwidths up to 1.1 MHz. 8.2 Functional Block Diagram + ± + ± IN+ IN- GND V S REF1 REF2 OUT 8.3 Feature Description 8.3.1 Amplifier Input Common-Mode Signal The INA296x supports large input common-mode voltages from –5 V to +110 V. The internal topology of the INA296x allows the common-mode range to exceed the power-supply voltage (VS). This allows for the INA296x to be used for low-side, inline, and high-side current-sensing applications that extend beyond the supply range of 2.7 V to 20 V. 8.3.1.1 Input-Signal Bandwidth The INA296x is available with several gain options including 10 V/V, 20 V/V, 50 V/V, 100 V/V, and 200 V/V. The unique multistage design enables the amplifier to achieve high bandwidth of 1.1 MHz at all gains. This high bandwidth provides the throughput and fast response that is required for the rapid detection and processing of over-current events. 8.3.1.2 Low Input Bias Current The INA296x inputs draw 35 µA (typical) bias current per input pin at common-mode voltages as high as 110 V, which enables precision current sensing on applications that require lower current leakage. Unlike many high voltage current sense amplifiers whose input bias currents are proportional to the common-mode voltage, the input bias current of the INA296x remains constant over the entire common-mode voltage range. 8.3.1.3 Low VSENSE Operation The INA296x features high performance operation across the entire valid VSENSE range. The zero-drift input architecture of the INA296x provides the low offset voltage and low offset drift needed to measure low VSENSE levels accurately across the wide operating temperature of –40°C to +125°C. Low VSENSE operation is particularly beneficial when using low ohmic shunts for low current measurements, as power losses across the shunt are significantly reduced.
