Detailed Description
The MAX4027 combines three 2:1 multiplexers with
+2V/V (+6dB) closed-loop gain (AVCL) amplifiers. This
low-power, high-speed device operates from ±5V sup-
plies, while driving up to two back-terminated video
loads with very low distortion. Differential gain and
phase errors are 0.012%/0.014° for the MAX4027.
The input multiplexers feature fast 15ns channel-
switching times and small switching transients. The
multiplexers also feature high input resistance and con-
stant input capacitance, so overall input impedance
can be set by external input-terminating resistors.
Drive EN high to place the amplifier outputs in a high-
impedance state, and minimize the supply current. This
function allows use of multiple mux/amps in parallel to
form large switching arrays.
The MAX4027 features an A/B input, which selects
either channel A or B. Drive A/B low to select channel A
or drive A/B high to select channel B. Channel A is
automatically selected if A/B is left unconnected.
Applications Information
Disable Mode
Drive EN high to place the MAX4027 in disable mode.
Placing the device in disable mode reduces the quies-
cent current to 17mA (VCC) and 15mA (VEE) and places
the amplifier outputs into a high-impedance state, typi-
