TDA1387T is a digital-to-analog converter chip launched by Philips, using 1.0µm CMOS process, with extremely low power consumption, low distortion and wide dynamic range.
The Philips TDA1387T is a stereo Continuous Calibration Digital-to-Analogue Converter (CC-DAC) designed for portable digital audio equipment. It utilizes an innovative internal charge storage principle to ensure high accuracy that remains insensitive to ageing, temperature, and process variations.
Fabricated in a 1.0 µm CMOS process, the device features low power consumption with a single supply voltage range of 3 to 5.5 V. The TDA1387T supports fast settling times enabling oversampling modes (2x, 4x, or 8x) and includes an internal bias current to maximize dynamic range while precluding zero-crossing distortion.
| Supply Voltage (Vop) | 3.0 to 5.5 V |
|---|---|
| Total Harmonic Distortion + Noise | -88 dB (typical) |
| Signal-to-Noise Ratio | 98 dB (typical, A-weighted) |
| Output Resolution | 16 bits |
| Operating Temperature Range | -40 to +85 °C |
| Supply Current (at code 0000H) | 6.5 mA (typical, Vop=5V) |
| Full Scale Output Current | 1.0 mA (typical, Vop=5V) |
| Clock Frequency | 18.4 MHz (typical) |
The device operates with a single supply rail ranging from 3 to 5.5 V.
It is eminently suitable for use in portable digital audio equipment.
No, it features no zero-crossing distortion due to its symmetrical offset decoding method.
