4-Tone WCDMA Waveform,
LT1993-10 Driving LTC2255
14-Bit ADC at 92.16Msps
700MHz Low Distortion, Low
Noise Differential Amplier/
ADC Driver (AV = 10V/V)
The LT1993-10 is a low distortion, low noise Differential
Amplier/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. Exception-
ally 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 unltered
outputs (+OUT and –OUT), the LT1993-10 has a built-in
175MHz differential lowpass lter and an additional pair
of ltered outputs (+OUTFILTERED, –OUTFILTERED) to
reduce external ltering 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 LT1993-10 is designed to meet the demanding require-
ments of communications transceiver applications. It can
be used as a differential ADC driver, a general-purpose
differential gain block, or in any other application requir-
ing differential drive. The LT1993-10 can be used in data
acquisition systems required to function at frequencies
down to DC.
The LT1993-10 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.
