TDA1314T is a high dynamic range quad low noise DAC for automotive audio systems, controlled by the automotive audio DSP. It features 18-bit data input format, four-times serial oversampling filter, 1st-order 4fas noise shaper and four very low noise DACs.
The TDA1314T is a quadruple very low noise high dynamic range DAC designed for use in motor cars and controlled by the car radio DSP. Each channel incorporates an 8th-order IIR up-sampling filter from 1ASF to 4ASF followed by a 1st-order noise shaper and DAC.
The device features four very low noise DACs requiring only 1st-order analog post filtering. It supports high dynamic range to enable digital DSP volume control with an 18-bit data input format for each of the four channels.
| Resolution | 18 bits |
|---|---|
| Total Harmonic Distortion plus Noise-to-Signal Ratio | -66 to -56 dB |
| Dynamic Range of DAC | 92 to 96 dB |
| Digital Silence (DS) | -110 to -100 dB |
| Total Power Dissipation | 85 mW |
| Operating Ambient Temperature | -40 to +85 °C |
The TDA1314T can operate in an ambient temperature range from -40 to +85 °C.
The up-sample filter provides an attenuation of at least 29 dB for out-of-band signals.
