ML2340*, ML2350**

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,

, ¹/

provide 8-, 9-, 10-, or 11-bit effective resolution

around zero

■ AGND to V output voltage swing

■ Bipolar or unipolar output voltage

scale (V ) in the unipolar mode or around zero scale

(V ) in the bipolar mode, both with programmable gain.

■ 4.5V to 13.2V single supply or ±2.25V to ±6.5V

can be set to any voltage from AGND to 2.25V below

. The digital and analog grounds, DGND and AGND,

dual-supply operation

■ Transparent latch allows microprocessor interface

are totally independent of each other. DGND can be set to

with 30ns setup time

any voltage from AGND to 4.5V below V for easy

■ Data flow-through mode

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.

ML2340 ........................................... 2.25V or 4.50V

ML2350 ........................................... 2.50V or 5.00V

■ Nonlinearity....................................±¹/

LSB or ±¹/

LSB

■ Output voltage settling time over temperature and

supply voltage tolerance

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.

Within 1V of V and AGND ................... 2.5µs max

Within 100mV of V and AGND ............... 5µs max

■ TTL and CMOS compatible digital inputs

■ Low supply current (5V supply) ..................... 5mA max

■ 18-pin DIP or surface mount SOlC
