1 / 10 page TLC7628C, TLC7628E, TLC7628I DUAL 8-BIT MULTIPLYING DIGITAL-TO-ANALOG CONVERTERS SLAS063A – APRIL 1989 – REVISED MAY 1995 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Easy Microprocessor Interface D On-Chip Data Latches D Digital Inputs Are TTL-Compatible With 10.8-V to 15.75-V Power Supply D Monotonic Over the Entire A/D Conversion Range D Fast Control Signaling for Digital Signal Processor (DSP) Applications Including Interface With TMS320 D CMOS Technology KEY PERFORMANCE SPECIFICATIONS Resolution Linearity Error Power Dissipation Settling Time Propagation Delay Time 8 bits 1/2 LSB 20 mW 100 ns 80 ns description The TLC7628C, TLC7628E, and TLC7628I are dual, 8-bit, digital-to-analog converters (DACs) designed with separate on-chip data latches and feature exceptionally close DAC-to-DAC matching. Data is transferred to either of the two DAC data latches through a common, 8-bit input port. Control input DACA/DACB determines which DAC is loaded. The load cycle of these devices is similar to the write cycle of a random-access memory, allowing easy interface to most popular microprocessor buses and output ports. Segmenting the high-order bits minimizes glitches during changes in the most significant bits, where glitch impulse is typically the strongest. The TLC7628C operates from a 10.8-V to 15.75-V power supply and is T TL-compatible over this range. 2- or 4-quadrant multiplying makes these devices a sound choice for many microprocessor-controlled gain-setting and signal-control applications. The TLC7628C is characterized for operation from 0 °C to 70°C. The TLC7628I is characterized for operation from – 25 °C to 85°C. The TLC7628E is characterized for operation from –40°C to 85°C.
