Description

The ML2003CP is an IC chip that falls under the category of Electronic Component Models. It is a digitally controlled logarithmic gain/attenuator that can provide a range of -24dB to +24dB, in steps of 0.1 dB. It can select gain settings through a 9-bit digital word. ML2003CP has two digital interfaces, parallel or serial, whereas ML2004 is packaged in a 14-pin DIP with a serial interface only.

Specifications and features

• Low noise: 0dBrnc 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

Application Scenarios

The ML2003CP can be used in various electronic circuits that require a logarithmic gain/attenuator subsystem. This includes audio equipment, radio frequency (RF) systems, and instrumentation circuits.

Comparison

• Low noise and low harmonic distortion leads to high quality audio and RF system applications
• Fine resolution gain step provides accurate gain control
• Flat frequency gain response for a broad range of frequencies

• ML2004 is only available in a serial interface, which may not suit certain applications
