PIN DESCRIPTIONS PACKAGE NAME DESCRIPTION 16-Pin 24-PIN 1 22 LDAC Load DACs 2 11 ADDR0 3-state address input 3 2 AVDD Power-supply input, 2.7V to 5.5V 4 3 VOUTA Analog output voltage from DAC A 5 4 VOUTC Analog output voltage from DAC C 6 5 VOUTE Analog output voltage from DAC E 7 6 VOUTG Analog output voltage from DAC G 8 8 VREFIN Positive reference input 9 12 CLR Asynchronous clear input 10 13 VOUTH Analog output voltage from DAC H 11 14 VOUTF Analog output voltage from DAC F 12 15 VOUTD Analog output voltage from DAC D 13 16 VOUTB Analog output voltage from DAC B 14 17 GND Ground reference point for all circuitry on the device Serial data input. Data are clocked into or out of the input register. This pin is a bidirectional, 15 19 SDA open-drain data line that should be connected to the supply voltage with an external pull-up resistor. 16 20 SCL Serial clock input. Data can be transferred at rates up to 3.4MHz. Schmitt-trigger logic input. — 1 NC Not internally connected — 7 NC Not internally connected — 9 RSTSEL Reset select pin. RSTSEL high resets device to mid-scale; RSTSEL low resets device to zero-scale. — 10 ADDR1 3-state address input — 18 NC Not internally connected Twos complement select. If the TWOC pin is pulled high, the DAC registers use twos complement — 21 TWOC format; if TWOC is pulled low, the DAC registers use straight binary format. — 23 NC Not internally connected — 24 NC Not internally connected Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s): DAC5578 DAC6578 DAC7578 |
