Product Overview

The PGA870IRHDT is a wideband fully differential Programmable Gain Amplifier for high-speed signal chain and data acquisition systems. The PGA870 has been optimized to provide high bandwidth, low distortion and low noise, making it ideally suited as a 14-bit analog-to-digital converter (ADC) driver for wireless base station signal chain applications. The wide gain range of -11.5 to +20dB can be adjusted in 0.5dB gain steps through a 6-bit control word applied to the parallel interface. The gain control interface may be configured as a level-triggered latch or an edge-triggered latch or it may be placed in an unlatched (transparent) mode. In addition to the 6-bit gain control, the PGA870 contains a power-down pin (PD) that can be used to put the device into a low-current, power-down mode. In this mode, the quiescent current drops to 2mA, but the gain control circuitry remains active, allowing the gain of the PGA870 to be set before device power-up.
  • Low impedance and voltage mode output
  • Flexible gain control interface
  • 2mA Low disable current
  • 2900V/µs Typical slew rate
  • 76dB Typical CMRR
  • Green product and no Sb/Br
