General Description
The Comlinear CLC503 is a single-ended to differential amplifier.
It utilizes a pair of closed-loop transconductance amplifiers to
provide wideband, high fidelity, differential output signals. Internal
resistors set the differential gain to 2V/V. With a ground-centered
2V
pp
input signal, the CLC503 will produce a 4V
pp
differential
output signal. This differential output signal is centered around an
adjustable common mode voltage. An independent input controls
the common mode output voltage. The CLC503 has harmonic
distortion products of -77dBc or less, and a signal to noise ratio of
72dB. The output stage is optimized for loads with signal ranges
between +0.7 and +3.9 volts, such as those found on single
supply CMOS ADCs. Overdrive recovery time of the CLC503
and following circuitry is optimized by the output limiting of the
CLC503. The power down pin (P
DN
) allows for power savings
in applications where unused circuitry is placed in a low
power mode.
The CLC503 is an ideal amplifier to drive the differential inputs
of the Comlinear CLC949, 12-bit, 20MSPS, analog-to-digital
converter. It is tailored for driving single supply, differential
input, analog-to-digital converters which require fast settling, high
fidelity inputs.
