Overview

Unity-Gain Bandwidth of 70MHz
Low Input Capacitance: 4pF
No Frequency Compensation Required
Low Input Blas Current: 100pA
Directly Drives 75Ω Cables
High Isolation Between Amplifiers: 72dB at 5MHz
Low Offset Voltage: 2mV

The MAX457 contains two unity-gain stable video amplifiers that are capable of driving the 75Ω loads with a -3dB bandwidth of 70MHz. The amplifiers operate from ±5V supplies and together consume about 350mW of power. Closed loop again is set by tow external resistors. The pinout of the MAX457 follows that of conventional 8-pin, dual op amps.

The amplifiers require no external compensation and because of the CMOS process offer low input bias current of typically 100pA. The isolation between the amplifiers is typically 72dB at 5MHz and differential phase and gain are 0.2 degrees and 0.5% respectively.
