MP7226

BiCMOS

Fixed, Quad, Voltage Output, Single or Dual

Supply 8-Bit Digital-to-Analog Converter

FEATURES

APPLICATIONS

• MPS Pioneered Segmented DAC Approach

• Four 8-Bit DACs with Buffer Amplifiers

• Function Generators

• Automatic Test Equipment

• Bipolar Amplifier Inputs for Low Noise and Drift • Process Controls

• Operates with Single or Dual Supplies

BENEFITS

• µP Compatible (95ns WR)

• No External Adjustments Required

• Power-on-Reset Function

• Specified for 5 to 15 V Operation

• ESD Protection: 2000 Volts Minimum

• Latch-Up Proof

• Reduced Board Space; Lower System Cost

• Reduced System Errors due to Excellent DAC-to-DAC

Matching and Tracking

• Easy to Design with Microprocessors

• Stable, High Reliability through Advanced Processing

• Lower 1/f Noise Increases Useful Dynamic Range

• Octal Available: MP7228

The MP7226 is manufactured using advanced thin film resis-

tors on a double metal BiCMOS process. The MP7226 incorpo-

rates a unique bit decoding technique yielding lower glitch,

higher speed and excellent accuracy over temperature and

time. The MP7226 maintains 8-Bit accuracy over the full operat-

ing temperature range without laser trim or external adjust-

ments.

GENERAL DESCRIPTION

The MP7226 contains four 8-bit voltage-output Digital-to-

Analog Converters, with BiCMOS output buffer amplifiers and

interface logic on a monolithic chip. Separate on-chip latches

are provided for each of the four D/A converters. The control

logic is speed compatible with most 8-bit microprocessors. All

digital inputs are TTL/CMOS(5V) compatible.
