Product Overview

AD8432ACPZ-WP is a dual-channel, ultralow noise amplifier with selectable gain and input impedance. Each channel has a single-ended input, differential output, and integrated input clamps. The exceptional noise performance of the device is made possible by active impedance matching. Using a feedback network, the input impedance of the amplifiers can be adjusted to match the signal source impedance without compromising the noise performance. Impedance matching and low noise in the device allow designers to create wider dynamic range systems that are able to detect even very low-level signals. It achieves 0.85nV/√Hz input-referred voltage noise for a gain of 12.04dB. It is used in applications such as CW Doppler ultrasound front ends, low noise preamplification, pre-driver for I/Q demodulators and phase shifters, and wideband analogue-to-digital drivers.
  • Active input impedance matching, integrated input clamp diode
  • Single-ended input, differential output, supply voltage range from 4.5V to 5.5V
  • Gain error is 0.1dB typical at (VS = 5V, TA = 25°C, RS = RIN = 50 ohm, RFB =150 ohm)
  • 200MHz typical -3dB small signal bandwidth at (G = 12.04dB, VS = 5V, TA = 25°C, RS = RIN = 50 ohm)
  • Slew rate (rising edge) is 295V/μs typical at (VOUT = 2V p-p, f = 10MHz, VS = 5V, TA = 25°C)
  • Input voltage noise is 0.85nV/√Hz typical at (VS = 5V, TA = 25°C, RS = RIN = 50 ohm)
  • Input offset voltage is +1mV typical at (VS = 5V, TA = 25°C, RS = RIN = 50 ohm, RFB =150 ohm)
  • Supply voltage range from 4.5V to 5.5V, quiescent current is 24mA typ at (ENB = 5V)
  • Power supply rejection ratio is -82dB typical at (G = 24.08dB, f = 100KHz, no bypass capacitors)
  • Operating temperature range from -40°C to +85°C, 24-lead LFCSP package
