The device features an initial gain of 20 V/V, with a 2.2 MHz bandwidth with a maximum ±0.13% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8410A has a minimum DC mon-mode rejection ratio (CMRR) of 123 d B from - 2 V to +70 V. The AD8410A performs bidirectional current measurements across a shunt resistor in a variety of industrial and automotive applications. The AD8410A offers breakthrough performance throughout the - 40°C to +125°C temperature range. The device features an in-package trim core, which leads to a typical offset drift of ±0.21 µV/°C (based on Box Method, see Figure 56) throughout the operating temperature range and the mon-mode voltage range without the need for chopping and autozero clocks (which could lead to intermodulation in the application). The device includes circuitry to achieve a wide input mon-mode range and balanced input bias currents, regardless of input differential voltage or mon-mode voltage, and circuitry...
