1 / 29 page DAC0830, DAC0832 www.ti.com SNAS534B – MAY 1999 – REVISED MARCH 2013 DAC0830/DAC0832 8-Bit μP Compatible, Double-Buffered D to A Converters Check for Samples: DAC0830, DAC0832 1 FEATURES KEY SPECIFICATIONS 234 • Double-Buffered, Single-Buffered or Flow- • Current Settling Time: 1 μs Through Digital Data Inputs • Resolution: 8 bits • Easy Interchange and Pin-Compatible with 12- • Linearity: 8, 9, or 10 bits (Ensured Over bit DAC1230 Series Temp.) • Direct Interface to All Popular • Gain Tempco: 0.0002% FS/°C Microprocessors • Low Power Dissipation: 20 mW • Linearity Specified with Zero and Full Scale • Single Power Supply: 5 to 15 VDC Adjust Only—NOT BEST STRAIGHT LINE FIT. • Works with ±10V Reference-Full 4-Quadrant DESCRIPTION Multiplication The DAC0830 is an advanced CMOS/Si-Cr 8-bit • Can Be Used in the Voltage Switching Mode multiplying DAC designed to interface directly with the 8080, 8048, 8085, Z80®, and other popular • Logic Inputs Which Meet TTL Voltage Level microprocessors. A deposited silicon-chromium R-2R Specs (1.4V Logic Threshold) resistor ladder network divides the reference current • Operates “STAND ALONE” (without μP) if and provides the circuit with excellent temperature Desired tracking characteristics (0.05% of Full Scale Range maximum linearity error over temperature). The circuit • Available in 20-Pin SOIC or PLCC Package uses CMOS current switches and control logic to achieve low power consumption and low output leakage current errors. Special circuitry provides TTL logic input voltage level compatibility. Double buffering allows these DACs to output a voltage corresponding to one digital word while holding the next digital word. This permits the simultaneous updating of any number of DACs. The DAC0830 series are the 8-bit members of a family of microprocessor-compatible DACs (MICRO- DAC).
