The current-sense amplifiers have a 5V to 32V common-mode input range and provide a voltage output that is a multiple of the sense voltage. The common-mode input range is independent of supply voltage. An external sense resistor determines the range of current monitored by a current-sense amplifier. Gains of 2 or 10 are available with a typical input-referred offset voltage of zero or 3mV. The 3mV offset option is ideal for applications where offset nulling is required.
The drive amplifiers provide up to ±10mA of output current capability and a high output capacitive load tolerance. Output transients are limited to ±100mV during power-up and power-down events. The drive amplifiers feature a digitally controllable fast output clamp to ground. The drive amplifier outputs are current limited and are offered with gains of 2 or 4.
The drive amplifiers draw approximately 4.75mA, while the current-sense amplifiers draw approximately 250µA with full-scale sense inputs. In shutdown mode, the total supply current reduces to less than 1µA.
The MAX1350–MAX1357 are available in a 20-pin TSSOP package and operate over the extended (-40°C to +85°C) temperature range.
