This document describes the functionality and features of the SSM2017 self-contained audio preamplifier. The preamplifier features excellent noise performance, ultra-low THD, wide bandwidth, high slew rate, true differential inputs, and low cost. It is suitable for applications such as audio mix consoles, intercom/paging systems, two-way radios, sonar, and digital audio systems.
The SSM2017 is a self-contained audio preamplifier designed for applications such as audio mix consoles, intercom systems, and digital audio. It features excellent noise performance, ultralow total harmonic distortion (THD), and a wide bandwidth. The device requires only one external gain set resistor and is available in various package types including 8-pin Mini-DIP and 16-pin SOIC.
| Total Harmonic Distortion Plus Noise (THD+N) | < 0.01% @ G = 100 |
|---|---|
| Input Referred Voltage Noise Density | 950 pV/ √Hz |
| Slew Rate | 17 V/ µs typ |
| Small Signal Bandwidth | 4000 kHz @ G = 1 |
| Operating Temperature Range | -40 °C to +85 °C |
| Supply Voltage Range | ±6 V to ±22 V |
| Maximum Gain | 70 dB |
The voltage gain G is calculated as G = 10kΩ / RG + 1.
Yes, it requires only one external gain set resistor or potentiometer.
Metal-film or wire-wound resistors are recommended.
