Analog Devices (MAX4372TEUK+T) Current Sense Amplifier, High Side

Current Sense Amplifier, High Side, Micropower, 1 Amplifier, 2 µA, SOT-23, 5Pins, -40 °C, 85 °CProduct OverviewThe MAX4372TEUK+T is a low cost, micropower, high side current sense amplifierwith voltage output in 5 pin SOT-23 package. The high side current monitoring isespecially useful in battery powered systems since it does not interfere withthe ground path of the battery charger. The input common mode range of 0 to 28Vis independent of the supply voltage and ensures that current-sense feedbackremains viable even when connected to a 2-cell battery pack in deep discharge.This device operates from a single supply and consumes only 30µA supply current.It has a voltage output that eliminates the need for gain setting resistors anddevice offers a high level of integration and flexibility which is ideal forapplications where battery/DC current monitoring is critical.Supply voltage range is 2.7V to 28VOperating temperature range from -40°C to 85°CLow cost, compact current sense solutionFull scale accuracy is 0.18%Input offset voltage is 0.3mVLow output impedance of 1.5ohmGain of current sense amplifier is 20V/VCommon mode rejection is 85dB, power supply rejection is 85dB275KHz of -3dB bandwidth at VSENSE = 20mV, gain = 20V/VCapacitive load stability is 1000pFApplicationsSensing & Instrumentation, Signal Processing, Industrial, Portable DevicesProduct InformationNo. of Amplifiers: 1 AmplifierInput Bias Current: 2µAAmplifier Case Style: SOT-23No. of Pins: 5PinsOperating Temperature Min: -40°COperating Temperature Max: 85°CBandwidth: 275kHzSupply Voltage Min: 2.7VSupply Voltage Max: 28VInput Offset Voltage: 300µVCMRR: 85dBMSL: MSL 1 - Unlimited
