DAC8554IPWR

Texas Instruments · Digital To Analog Converters (DAC) · TSSOP-16

DAC8554IPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUTA output Analog output from DAC channel A, range 0V to VREFH with ±12LSB accuracy.
2 VOUTB output Analog output from DAC channel B, range 0V to VREFH with ±12LSB accuracy.
3 VrefH input Positive reference voltage input, valid range 0V to AVDD with input impedance 31kΩ typical.
4 AVDD power_in Analog supply input, 2.7V to 5.5V with typical current 600-900µA for all active channels at 5V.
5 VrefL input Negative reference voltage input, valid range 0V to AVDD/2 with input impedance 31kΩ typical.
6 GND power_in Ground reference point for all circuitry, single ground pin carrying all return currents.
7 VOUTC output Analog output from DAC channel C, range 0V to VREFH with ±12LSB accuracy.
8 VOUTD output Analog output from DAC channel D, range 0V to VREFH with ±12LSB accuracy.
9 SYNC input Level-triggered frame synchronization input (active LOW), gates data transfer on falling SCLK edges.
10 SCLK input Serial clock input for SPI interface, supports up to 50MHz at IOVDD = 5V.
11 DIN input Serial data input for 24-bit shift register, clocked on falling edges of SCLK.
12 IOVDD power_in Digital power supply input, 1.8V to 5.5V, powers logic inputs independent of AVDD.
13 A0 input Address selection input bit 0, sets device address on shared SPI bus.
14 A1 input Address selection input bit 1, sets device address on shared SPI bus.
15 ENABLE input Active LOW serial interface enable, connect to logic low for normal SPI operation.
16 LDAC input Load DAC rising-edge trigger input, asynchronously loads all four DAC registers simultaneously.
