LT1993-10

The LT^®1993-10 is a low distortion, low noise Differential Amplifi er/ADC driver for use in applications from DC to 700MHz. The LT1993-10 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 LT1993-10 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 LT1993-10 has a built-in 175MHz differential lowpass fi lter and an additional pair of fi ltered outputs (+OUTFILTERED, OUTFILTERED) to reduce external fi ltering components when driving high speed ADCs. The output common mode voltage is easily set via the V_OCM pin, eliminating either an output transformer or AC-coupling capacitors in many applications.

The LT1993-10 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. It can be used in data acquisition systems required to function at frequencies down to DC.

The device 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.
