LT1990IS8-10#PBF

LT1990-10 is a micropower precision difference amplifier with a very high common mode input voltage range, a fixed gain of 10 and 100KHz bandwidth. This device operates over a ±250V common mode voltage range on a ±15V supply. The inputs are fault protected from common mode voltage transients upto ±350V and differential voltages upto ±500V. It is ideally suited for both high side and low side current or voltage monitoring. The rail-to-rail output maximizes the dynamic range, especially important for single supplies as low as 2.7V. It is used in applications such as battery cell voltage monitoring, high voltage current sensing, signal acquisition in noisy environments, input protection, fault protected front ends, level sensing, isolation.

• Common mode rejection ratio is 72dB typical at (VCM = -5V to 25V, VREF = 1.25V)
• Gain error is 0.8% maximum at (VOUT = 0.5V to (+VS) -0.75V)
• Power supply rejection ratio is 92dB typical at (VS = 2.7V to 12.7V, VCM = VREF = 1.25V)
• High input impedance: 2Mohm differential, 500Kohm common mode
• Wide supply voltage range from 2.7V to 36V, rail-to-rail output
• Input noise voltage is 30µVP-P typical at (fO = 0.1Hz to 10Hz, TA = 25°C)
• Supply current is 160µA typical at (TA = 25°C)
• Slew rate is 1V/µs typical, settling time to 0.01% is 20µs typical
• Operating temperature is -40°C to 85°C
• Package style is 8-lead NSOIC
