ML2004 - Logarithmic Gain/Attenuator

General Description

The ML2003 and ML2004 are digitally controlled logarithmic gain/attenuators with a range of

24 to +24 dB in 0.1 dB steps.

The gain settings are selected by a 9-bit digital word.

The ML2003 digital interface is either parallel or serial.

Key Features

  • Low noise: 0 dBrnc max with +24dB gain Low harmonic distortion: -60dB max Gain range:.
  • 24 to +24dB Resolution: 0.1dB steps Flat frequency response: ±0.05dB from .3.
  • 4 kHz ±0.10dB from .1-20 kHz.
  • Low supply current 4mA max from ±5V supplies.
  • TTL/CMOS compatible digital interface.
  • ML2003 has pin selectable serial or parallel interface; ML2004 serial interface only General.
