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 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.
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.
