Description

The AD8410A is a high voltage, high bandwidth current-sense amplifier. 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 common-mode rejection ratio (CMRR) of 123 dB 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 common-mode voltage range without the need for chopping and autozero clocks (which could lead to intermodulation in the application). The device in- cludes circuitry to achieve a wide input common-mode range and balanced input bias currents, regardless of input differential voltage or common-mode voltage, and circuitry to achieve ultra-low CMRR drift. The device also includes circuitry to enable output accuracy in the presence of pulse-width modulation (PWM) type input common-mode voltages. The AD8410A is available in 8-lead, SOIC_N package and 8-lead, MSOP package.APPLICATIONSIn-phase or High-side current sensing inMotor control in BLDC motors, Low-inductance motorsBidirectional 48 V to 12 V DC-DC convertersSolenoid controlsPower rail monitoringLow-side current sensingDatacenter power supply unit (PSU) and battery backup unit (BBU)Protected by U.S. patent numbers 10,312,865 and 10,587,228.
