Description

The DAC8043A is an improved high accuracy 12-bit multiplying digital-to-analog converter in space-saving 8-lead packages. Featuring serial input, double buffering and excellent analog performance, the DAC8043A is ideal for applications where PC board space is at a premium. Improved linearity and gain error performance permit reduced parts count through the elimina
tion of trimming components. Separate input clock and load DAC control lines allow full user control of data loading and analog output. The circuit consists of a 12-bit serial-in/parallel-out shift register, a 12-bit DAC register, a 12-bit CMOS DAC and control logic. Serial data is clocked into the input register on the rising edge of the CLOCK pulse. When the new data word has been clocked in, it is loaded into the DAC register with the LD input pin. Data in the DAC register is converted to an output current by the D/A converter.

Part Number: AD679TD

Function: 14-bit, 128 kSPS, complete sampling ADC

Package: DIP 28 Pin Type

Manufacturer: Analog Devices

Description

The AD679TD is a complete, multipurpose 14-bit monolithic analog-to-digital converter, consisting of a sample-and-hold amplifier (SHA), a microprocessor-compatible bus interface, a voltage reference, and clock generation circuitry.

The AD679 is specified for ac (or dynamic) parameters such as S/N+D ratio, THD, and IMD, which are important in signal processing applications. In addition, the AD679K, B, and T
grades are fully specified for dc parameters that are important in measurement applications.

The 14 data bits are accessed in two read operations (8 + 6), with left justification. Data format is straight binary for unipolar mode and twos complement binary for bipolar mode. The input has a full-scale range of 10 V with a full power bandwidth of 1 MHz and a full linear bandwidth of 500 kHz. High input impedance (10 MΩ) allows direct connection to unbuffered
sources without signal degradation. Conversions can be initiated either under microprocessor control or by an external clock asynchronous to the system clock.

Features

1. 128k Conversions per Second

2. 1 MHz Full Power Bandwidth

3. 500 kHz Full Linear Bandwidth

4. 78 dB S/N+D (K, B, T Grades)

5. Twos Complement Data Format (Bipolar Mode)

6. Straight Binary Data Format (Unipolar Mode)

7. On-Board Reference and Clock

8. 10 V Unipolar or Bipolar Input Range
