GENERAL DESCRIPTION
The ML2004 is packaged in a 14-pin DIP with a serial interface only. Absolute gain accuracy is 0.05dB max over supply tolerance of ±10% and temperature range. These CMOS logarithmic gain/attenuators are designed for a wide variety of applications in telecom, audio, sonar, or general purpose function generation. One specific intended application is analog telephone lines.
