The LT1993-2 is a low distortion, low noise Differential Amplifier/ADC driver for use in applications from DC to 800MHz. The LT1993-2 has been designed for ease of use, with minimal support circuitry required. Exceptionally low input-referred noise and low distortion products (with either single-ended or differential inputs) make the LT1993-2 an excellent solution for driving high speed 12-bit and 14-bit ADCs. In addition to the normal unfi ltered outputs (+OUT and –OUT), the LT1993-2 has a built-in 175MHz differential low pass filter and an additional pair of filtered outputs (+OUTFILTERED, –OUTFILTERED) to reduce external filtering components when driving high speed ADCs. The output common mode voltage is easily set via the VOCM pin, eliminating either an output transformer or AC-coupling capacitors in many applications.
The LT1993-2 is designed to meet the demanding requirements of communications transceiver applications. It can be used as a differential ADC driver, a general-purpose differential gain block, or in any other application requiring differential drive. The LT1993-2 can be used in data acquisition systems required to function at frequencies down to DC.
The LT1993-2 operates on a 5V supply and consumes 100mA. It comes in a compact 16-lead 3 × 3 QFN package and operates over a –40°C to 85°C temperature range.
