GENERAL DESCRIPTION
The TDA8702 is an 8-bit Digital-to-Analog Converter
(DAC) for video and other applications. It converts the
digital input signal into an analog voltage output at a
maximum conversion rate of 30 MHz. No external
reference voltage is required and all digital inputs are TTL
compatible.
QUICK REFERENCE DATA
Note
1. D0 to D7 connected to VCCD and CLK connected to DGND.
2. The analog output voltages (VOUT and VOUT) are negative with respect to VCCA (see Table 1). The output resistance
between VCCA and each of these outputs is typically 75 .
3. The
3 dB analog output bandwidth is determined by real time analysis of the output transient at a maximum input
code transition (code 0 to 255).
