SAA2003 is a single chip stereo filter and codec from Philips Semiconductors. It features a wide operating voltage range (2.7-5.5 V), low power consumption (98 mW, 3.0 V), sleep mode to reduce power consumption and electromagnetic interference (EMI), transparent serial audio data mode in sleep mode and IEC 958 digital output.
The Philips SAA2003 is an integrated circuit designed to perform sub-band filtering and audio IEC 958 digital output frame codec functions within the Precision Adaptive Sub-band Coding (PASC) system. It operates as a single-chip stereo filter and codec, suitable for use in DCC record systems where it works alongside an Adaptive Allocation and Scale Factor processor (SAA2013). The device supports three sample rates: 32 kHz, 44.1 kHz, and 48 kHz.
| Operating voltage range | 2.7 to 5.5 V |
|---|---|
| Power consumption (at 3.0 V) | 98 mW |
| Sample rates | 32 kHz, 44.1 kHz, 48 kHz |
| Package type | SOT307 (QFP) |
The device operates with a wide voltage range from 2.7 to 5.5 V.
It consumes 98 mW when powered by a 3.0 V supply.
The device supports three sample rates of 32 kHz, 44.1 kHz, and 48 kHz.
The reset signal must be active for more than 1 ms from system power-up.
