High Speed DAC

MS9714

  • In supply
High speed, low power digital to analog converter
Overview

The MS9708/MS9714 is a 8bit/14bit high-speed and low power dissipation DAC. When sample rate reaches 125MSPS, the MS9708/MS9714 can also provide perfect AC and DC characteristics.

The DVDD normal operating voltage ranges from +1.8V to +5.5V and the AVDD normal operating voltage ranges from +2.7V to +5.5V. The feature of low power dissipation can make it suitable for portable and low power dissipation products.

The MS9708/MS9714 adopts a segmented current source architecture and specialized switch technique, in order to reduce parasitic effect and improve dynamic characteristics. Edge-triggered latch and temperature compensated bandgap reference are integrated together so as to get a complete monolithic DAC solution.

Full-scale current output is 20mA and output impedance is more than 100kΩ. Complementary current output provides single-end or differential applications. Current output terminal can be connected with two output resistors, achieving two complementary, single-ended voltage outputs.

The MS9708/MS9714 includes a 1.2V internal reference and reference current control amplifier, which can set full-scale current by adjusting external resistor. The MS9708/MS9714 can also connect with external reference. The output current is from 2mA to 20mA without affecting dynamic characteristics.

The MS9708/MS9714 is available in TSSOP28 package.
