9 / 33 page Preliminary Technical Data AD5025/45/65 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS 1 2 3 4 5 6 7 AD5065/45/35 13 12 11 10 9 8 GND VOUTB K TOP VIEW (Not to Scale) PDL SCL CLR VrefB 14 DIN LDAC SYNC VDD VrefA VOUTA POR SDO Figure 5. 14-Lead TSSOP (RU-14) Table 6. Pin Function Descriptions Pin No. Mnemonic Description 1 LDAC Pulsing this pin low allows any or all DAC registers to be updated if the input registers have new data. This allows all DAC outputs to simultaneously update. Alternatively, this pin can be tied permanently low. 2 Active Low Control Input. This is the frame synchronization signal for the input data. When SYNC goes low, it powers on the SCLK and DIN buffers and enables the input shift register. Data is transferred in on the falling edges of the next 32 clocks. If SYNC is taken high before the 32nd falling edge, the rising edge of SYNC acts as an interrupt and the write sequence is ignored by the device. 3 SYNC Power Supply Input. These parts can be operated from 2.7 V to 5.5 V, and the supply should be decoupled with a 10 μF capacitor in parallel with a 0.1 μF capacitor to GND. 4 VDD Dac A reference input .This is the reference voltage input pin for Dac A. 5 VREFA Analog Output Voltage from DAC A. The output amplifier has rail-to-rail operation. 6 VOUTA POR Power-on Reset Pin. Tying this pin to GND powers up the part to 0 V. Tying this pin to VDD powers up the part to midscale. 7 SDO Serial Data Output. Can be used for daisy-chaining a number of these devices together or for reading back the data in the shift register for diagnostic purposes. The serial data is transferred on the rising edge of SCLK and is valid on the falling edge of the clock. 8 Asynchronous Clear Input. The CLR input is falling edge sensitive. When CLR is low, all LDAC pulses are ignored. When CLR is activated, the input register and the DAC register are updated with the data contained in the CLR code register—zero, midscale, or full scale. Default setting clears the output to 0 V. 9 CLR Dac B reference input .This is the reference voltage input pin for Dac B. 10 VREFB Analog Output Voltage from DAC B. The output amplifier has rail-to-rail operation. 11 VOUTB GND Ground Reference Point for All Circuitry on the Part. 12 PDL The PDL pin is used to ensure hardware shutdown lockout of the device under any circumstance. A Logic 1 at the PLO pin will cause the device to behave as normal. The user may successfully enter software power down over the serial interface while logic 1 is applied to the PDL pin. If a logic 0 is applied to this pin, it will ensure that the device cannot enter software power down under any circumstances. If the device had previously been placed in software power down mode, a high to low transition at the PDL pin will cause the DAC(s) to exit power down and the output the last code in the dac register before the device entered software power down. 13 DIN Serial Data Input. This device has a 32-bit shift register. Data is clocked into the register on the falling edge of the serial clock input. 14 SCLK Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial clock input. Data can be transferred at rates of up to 50 MHz. Rev. PrB | Page 9 of 3 3 |
