The LM7372 is a dual high-speed voltage feedback amplifier that has the slewing characteristics of current feedback amplifiers. It can be used in all traditional voltage feedback amplifier configurations. This device from National Semiconductor is stable for gains as low as +2 or -1. It provides a very high slew rate at 3000 V/µs and a wide gain-bandwidth product of 120 MHz, whereby current consumption is only 6,5 mA per amplifier. The device is ideal for video and high-speed signal processing applications such as xDSL and pulse amplifiers. With 150 mA output current, the LM7372 can be used for video distribution, as a transformer driver or as a laser diode driver.
The LM7372 offers high SFDR and low THD, highly suitable for ADC/DAC systems. In addition, it is specified for ±5 V operation for portable applications. The LM7372 is based on National Semiconductor's Advance VIP III (Vertically Integrated PNP) complementary bipolar process.
Features: -80 dBc maximum harmonic distortion @ 1 MHz, 2 VPP; -3 dB frequency @ AV = +2: 200 MHz; High open loop gain: 85 dB; Differential gain and phase error: 0,01%, 0,02°; Operating temperature range: -40 to 85°C; packages: LLP-8, PSOP-8, SOIC-16
National also has available the CLC730114 evaluation board, which is designed to aid in the characterisation of National's 8-pin dual op amps in LLP package.
