DESCRIPTIO

The LT
®
1995 is a high speed, high slew rate, gain select-
able amplifier with excellent DC performance. Gains from
–7 to 8 with a gain accuracy of 0.2% can be achieved using
no external components. The device is particularly well
suited for use as a difference amplifier, where the excellent
resistor matching results in a typical common mode
rejection ratio of 79dB.
The amplifier is a single gain stage design similar to the
LT1363 and features superb slewing and settling charac-
teristics. Input offset of the internal operational amplifier
is less than 2.5mV and the slew rate is 1000V/µs. The
output can drive a 150Ω load to ±2.5V on ±5V supplies,
making it useful in cable driver applications.
The resistors have excellent matching, 0.2% maximum at
room temperature and 0.3% from –40°C to 85°C. The
temperature coefficient of the resistors is typically
–30ppm/°C. The resistors are extremely linear with volt-
age, resulting in a gain nonlinearity of 10ppm.
The LT1995 is fully specified at ±2.5V, ±5V and ±15V sup-
plies and from –40°C to 85°C. The device is available in
space saving 10-lead MSOP and 10-Lead (3mm × 3mm)
DFN packages. For a micropower precision amplifier with
precision resistors, see the LT1991 and LT1996.
