Single Supply, Programmable  
8-Bit D/A Converters  
GENERAL DESCRIPTION  
FEATURES  
The ML2340 and ML2350 are CMOS voltage output, 8-bit  
D/A converters with an internal voltage reference and a µP  
interface. These devices are designed to be powered by a  
single supply, although they can be powered from dual  
power supplies. The output voltage swings above zero  
Programmable output voltage gain settings of 2, 1,

interfacing to standard TTL and CMOS logic families.  
Voltage reference output  
The high level of integration and versatility of the ML2340  
and ML2350 makes them ideal for a wide range of  
applications in hard disk drives, automotive, telecom, and  
a variety of general purpose industrial uses. One specific  
intended application is controlling a hard disk voice coil.

The internal reference of the ML2340 provides a 2.25V or  
4.50V output for use with A/D converters that use a single  
5V ±10% power supply, while the ML2350 provide a  
2.50V or 5.00V reference output.
