Description
VCA 261 3 VCA2613 SBOS179D * DECEMBER 2000 * REVISED OCTOBER 2004 Dual, VARIABLE GAIN AMPLIFIER with Low-Noise Preamp .
The VCA2613 is a dual, Low-Noise Preamplifier (LNP), plus low-noise Variable Gain Amplifier (VGA).
Features
* q LOW NOISE PREAMP: Low Input Noise: 1.0nV/√Hz Active Termination Noise Reduction Switchable Termination Value 80MHz Bandwidth 5dB to 25dB Gain Differential In and Out q LOW NOISE VARIABLE GAIN AMPLIFIER: Low Noise VCA: 3.3nV/√Hz, Differential Programming Optimizes Noise Figure 24dB to 45dB Gain 40M
Applications
* The output can be used in either a single-ended or differential mode to drive high-performance Analog-to-Digital (A/D) converters, and is cleanly limited for optimum overdrive recovery. The combination of low noise, gain, and gain range programmability makes the VCA2613 a versatile building block i
