AD5424 datasheet



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.

IL91531 Datasheet PDF – Parallel Input Tone / Pulse Dialer

Part Number: IL91531

Function: Parallel Input Tone / Pulse Dialer ( HIGH-PERFORMANCE SILICON-GATE CMOS )

Package: DIP 16 Pin Type

Manufacturer: Integral


IL91531 datasheet



The IN91531N provides a  4-bit data input and a handshaking signal to serve as microcomputer interfaces. Under microcomputer control the IN91531N generates both a DTMF signal and a pulse output for telephone dialing. All necessary dual -tone frequencies and dial pulse outputs are derived from the widely used TV crystal standard, providing high accuracy and stability. The required sinusoidal waveform for individual tones is digitally synthesized on the chip, resulting in a waveform with very low total harmonic distortion.


1. TTL compatible inputs and outputs
2. Uses TV crystal standard (3.58 MHz) to derive all frequencies, providing high accuracy and stability
3. Operating voltage: 2.5 to 5.5 Volts
4. Selectable M/B ratio
5. 10 PPS dial rate
6. High group tone pre-emphasis : 2 dB
7. Low total harmonic distortion in DTMF signaling
