Product Overview

The MAX457CSA+ is a dual, 70MHz video amplifier in 8 pin NSOIC package. It contains two unity gain stable video amplifiers that are capable of driving 75ohm loads with -3dB bandwidth of 70MHz. The amplifier operates from ±5V supplies and together consume about 350mW of power. Closed loop gain is set by two external resistors. The pin-out of MAX457 follows that of conventional 8 pin, dual op-amp. The amplifier requires no external compensation and because of CMOS process offer low input bias current of typically 100pA. The isolation between amplifiers is typically 72dB at 5MHz and differential phase and gain are 0.2degrees and 0.5% respectively. It is used in output amplifiers for video crosspoint switches, high speed, low gain applications, driving flash converters and video distribution amplifiers.
  • Supply voltage range from ± 4.5V to ± 5.5V
  • Operating temperature range from 0°C to 70°C
  • Low input capacitance of 4pF
  • No frequency is required and directly drives 75ohm cables
  • Low input bias current of 0.1nA at TA = 25°C
  • Slew rate of 300V/µs and -3dB bandwidth of 70MHz at Av = 0dB, RL = 75 ohm
  • Low offset voltage of 2mV and output voltage drift of 20µV/°C
  • Open loop voltage gain of 300V/V at RL = 1000ohm
  • CMRR of 66dB at -2V <= VIN <= 2V and PSRR of 66dB at ±4.5V to ±5.5V
  • Supply current of 35mA at TA = 25°C
