6 / 16 page Octal, 13-Bit Voltage-Output DAC with Parallel Interface 6 _______________________________________________________________________________________ PLCC NAME 1 – C — L — R – Clear Input (active low). Driving this asynchronous input low sets the content of all latches to 1000hex. All DAC outputs are reset to AGND_. 3 REFCD Reference Voltage Input for DAC C and DAC D. Bypass to AGNDCD with a 0.1µF to 1µF capacitor. 2 AGNDCD Analog Ground for DAC C and DAC D 7 VOUTB DAC B Output Voltage 6 VOUTC DAC C Output Voltage 5 VOUTD DAC D Output Voltage 4, 42 VSS Negative Power Supply, -5V (2 pins). Connect both pins to the supply voltage. Bypass each pin to the system analog ground with a 0.1µF to 1µF capacitor. FLAT PACK PIN 39 41 40 1 44 43 42, 36 FUNCTION 8 VOUTA DAC A Output Voltage 2 9, 37 VDD Positive Power Supply, 5V (2 pins). Connect both pins to the supply voltage. Bypass each pin to the system analog ground with a 0.1µF to 1µF capacitor. 3, 31 10 REFAB Reference Voltage Input for DAC A and DAC B. Bypass to AGNDAB with a 0.1µF to 1µF capacitor. 4 11 AGNDAB Analog Ground for DAC A and DAC B 5 12 – L — D — A — B – Load Input (active low). Driving this asynchronous input low transfers the contents of input latches A and B to the respective DAC latches. 6 13 – L — D — C — D – Load Input (active low). Driving this asynchronous input low transfers the contents of input latches C and D to the respective DAC latches. 7 14 – C — S – Chip Select (active low) 8 15 – W — R – Write Input (active low). – W — R – , along with – C — S – , loads data into the DAC input latch selected by A0–A2. 9 ADJACENT-CHANNEL CROSSTALK A: DIGITAL INPUTS, DAC A, DATA BITS from ALL Os to OAAAhex B: OUTPUT, DAC B 500ns/div REF– = 4.096V, CL = 50pF, RL = 10kΩ A 5V/div B 5mV/div ADJACENT-CHANNEL CROSSTALK A: DIGITAL INPUTS, DAC A, DATA BITS from OAAAhex to ALL Os B: OUTPUT, DAC B 500ns/div REF– = 4.096V, CL = 50pF, RL = 10kΩ A: 5V/div B: 5mV/div ______________________________________________________________Pin Description ____________________________Typical Operating Characteristics (continued) (VDD = 5V, VSS = -5V, REF_ = 4.096V, AGND_ = GND = 0V, TA = +25°C, unless otherwise noted.) |
