LT1995 32MHz, 1000V/s Gain Selectable Amplifier FEATURES DESCRIPTIO Internal Gain Setting Resistors The LT 1995 is a high speed, high slew rate, gain select- Pin Configurable as a Difference Amplifier, able amplifier with excellent DC performance. Gains from Inverting and Noninverting Amplifier 7 to 8 with a gain accuracy of 0.2% can be achieved using Difference Amplifier: no external components. The device is particularly well Gain Range 1 to 7 suited for use as a difference amplifier, where the excellent CMRR > 65dB resistor matching results in a typical common mode Noninverting Amplifier: rejection ratio of 79dB. Gain Range 1 to 8 The amplifier is a single gain stage design similar to the Inverting Amplifier: LT1363 and features superb slewing and settling charac- Gain Range 1 to 7 teristics. Input offset of the internal operational amplifier Gain Error: <0.2% is less than 2.5mV and the slew rate is 1000V/s. The Slew Rate: 1000V/s output can drive a 150 load to 2.5V on 5V supplies, Bandwidth: 32MHz (Gain = 1) making it useful in cable driver applications. Op Amp Input Offset Voltage: 2.5mV Max The resistors have excellent matching, 0.2% maximum at Quiescent Current: 9mA Max room temperature and 0.3% from 40C to 85C. The Wide Supply Range: 2.5V to 15V temperature coefficient of the resistors is typically Available in 10-Lead MSOP and 30ppm/C. The resistors are extremely linear with volt- 10-Lead (3mm 3mm) DFN Packages age, resulting in a gain nonlinearity of 10ppm.
