Product Overview
LT1990 is a micropower precision difference amplifier with a very high common mode input voltage range. It has pin selectable gains of 1 or 10. The LT1990 operates over a ±250V common mode voltage range on a ±15V supply. The inputs are fault protected from common mode voltage transients up to ±350V and differential voltages up to ±500V. The LT1990 is ideally suited for both high side and low side current or voltage monitoring. On a single 5V supply, the LT1990 has an adjustable 85V input range, 70dB min CMRR and draws less than 120µA supply current. The rail-to-rail output maximizes the dynamic range, especially important for single supplies as low as 2.7V. Application includes battery cell voltage monitoring, high voltage current sensing, signal acquisition in noisy environments, input protection, fault protected front ends, level sensing, isolation.
- Pin selectable gain of 1 or 10, Rail-to-Rail output
- 1 typical gain (Pins 5 and 8 = open, VS = 3V, 0V, TA = 25°C)
- 0.07% typical gain error (G = 1, VS = 3V, 0V, VS = 5V, 0V, TA = 25°C)
- Input voltage range from -5 to 25V (VS = 3V, 0V, VREF = 1.25V, TA = 25°C)
- 68dB typical common mode rejection ratio VS = 3V, 0V, TA = 25°C)
- 92dB typical power supply rejection ratio ( VS = 2.7V to 12.7V, VCM = VREF = 1.25V)
- 105µA typical supply current (VS = 3V, 0V, VS = 5V, 0V, RL = 10k)
- 100KHz typical bandwidth (–3dB, G = 1, TA = 25°C, VS = 3V, 0V, VS = 5V, 0V)
- 0.5V/µs typical slew rate (G = 1, VS = 5V, 0V, VOUT = 0.5V to 4.5V)
- 8 lead plastic SO package, operating temperature range from -40°C to 85°C
