The ML7000/ML7001 are single-channel CMOS CODEC LSI devices for voice signals ranging from 300 to 3400 Hz with filters for A/D and D/A conversion.
The ML7000/ML7001 series are single‑channel CMOS CODEC LST devices for voice signals (300‑3400 Hz) with integrated A/D and D/A filters. They are optimized for low‑power applications such as ISDN terminals, digital wireless systems, and digital PBXs, and can directly drive handset receivers.
Key features include a single‑supply operation (+5 V for ML7000, +3 V for ML7001), low power consumption (25 mW typical), selectable A‑law or µ‑law companding, built‑in PLL, adjustable transmit/receive gain, and a wide range of serial data rates up to 2048 kHz. The devices are offered in 24‑pin SOP and 20‑pin SSOP packages with detailed mechanical dimensions.
| Supply voltage | +5 V (ML7000) / +3 V (ML7001) |
|---|---|
| Operating power consumption | 25 mW (ML7000) / 20 mW (ML7001) |
| Power‑down consumption | 0.05 mW (ML7000) / 0.03 mW (ML7001) |
| Serial data rate | 64 kHz to 2048 kHz (multiple steps) |
The ML7000 operates from a single +5 V supply.
The SOP package has 24 pins.
