AD5424 datasheet

 

Description

The AD5424/AD5433/AD5445 are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respectively. These devices operate from a 2.5 V to 5.5 V power supply,making them suitable for battery-powered applications and many other applications. These DACs utilize data readback, allowing the user to read the contents of the DAC register via the DB pins. On power-up, the internal register and latches are filled with 0s and the DAC outputs are at zero scale. As a result of manufacturing with a CMOS submicron process, they offer excellent-quadrant multiplication characteristics, with large signal multiplying bandwidths of up to 10 MHz. The applied external reference input voltage (VREF) determines the full-scale output current. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output
when combined with an external I-to-V precision amplifier.

TDA8786A datasheet

 

Description

The TDA8786; TDA8786A is a 10-bit analog-to-digital interface for CCD cameras. The device includes a correlated double sampling circuit, AGC, a soft clipper circuit and a low power 10-bit Analog-to-Digital Converter (ADC) together with its reference voltage regulator. The AGC and soft clipper circuits are controlled by on-chip DACs via a serial interface. A 10-bit DAC controls the ADC input clamp level. A pre-blanking function is also included. An additional DAC is provided for additional system controls; its output voltage range is 1.4 V (p-p) which is available at pin OFDOUT.

Features

1. Fully programmable via a 3-wire serial interface
2. Sampling frequency up to 18 MHz
3. AGC gain from 3.5 to 33.5 dB (in 0.1 dB steps)
4. Programmable soft clipper for white compression
5. 8-bit and 10-bit DAC included for analog settings
6. TTL compatible inputs, TTL and CMOS compatible outputs.

Applications

1. CCD camera systems
