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 Description
The ML2003 and ML2004 are digitally controlled logarith-
mic 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.
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 gen-
eral purpose function generation. One specific intended
application is analog telephone lines.
