The MAX4144/MAX4145/MAX4146 differential line receivers offer unparalleled high-speed, low-distortion performance. Using a three op-amp instrumentation amplifier architecture, these ICs have fully symmetrical differential inputs and a single-ended output. They operate from ±5V power supplies and are capable of driving a 150Ω load to ±3.7V. The MAX4144 has an internally set closed-loop gain of +2V/V. The MAX4145 is optimized for gains from +1V/V to +10V/V, while the MAX4146 is optimized for gains from +10V/V to +100V/V. The MAX4145/MAX4146 require a single external resistor to set the closed-loop gain. These amplifiers use laser-trimmed, matched thin-film resistors to deliver a common-mode rejection (CMR) of up to 90dB at 10MHz. Using current-feedback tech- niques, the MAX4144 achieves a 130MHz bandwidth and a 1000V/µs slew rate. The MAX4145 achieves a bandwidth of 180MHz and a slew rate of 600V/µs while operating with a closed-loop gain of +1V/V, and the MAX4146 features a bandwidth of 70MHz and a slew rate of 800V/µs with a gain of +10V/V. Excellent differ- ential gain/phase and noise specifications make these amplifiers ideal for a wide variety of video and RF signal-processing applications.
