DAC11001APFBR

Texas Instruments · Digital To Analog Converters (DAC) · TQFP-48(7x7)

DAC11001APFBR from Texas Instruments, in a TQFP-48(7x7). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connection; leave floating.
2 AGND power_in Analog ground; connect to 0 V.
3 REFPF input External positive reference input.
4 REFPS input External positive reference sense node.
5 REFNF input External negative reference input; connect to 0 V for unipolar DAC output.
6 REFNS input External negative reference sense node.
7 OUT output Unbuffered voltage output.
8 AGND-OUT power_in Analog ground; connect to 0 V and measure the DAC output voltage with respect to this node.
9 RFB input Integrated precision resistor feedback node.
10 ROFS input Integrated precision resistor offset node.
11 RCM input Integrated precision resistor common-mode node.
12 NC unconnected No connection; leave floating.
13 NC unconnected No connection; leave floating.
14 AGND-TnH power_in Analog ground for the integrated deglitcher clock; connect to 0 V.
15 NC unconnected No connection; leave floating.
16 DGND power_in Digital ground; connect to 0 V.
17 DGND power_in Digital ground; connect to 0 V.
18 LDAC input Active-low load DAC input; it is used for synchronous updates and must be connected permanently to 0 V for asynchronous updates.
19 ALARM output Alarm output; ALARM to DGND is limited to -0.3 V to DVDD + 0.3 V.
20 DGND power_in Digital ground; connect to 0 V.
21 DGND power_in Digital ground; connect to 0 V.
22 DGND power_in Digital ground; connect to 0 V.
23 DGND power_in Digital ground; connect to 0 V.
24 NC unconnected No connection; leave floating.
25 NC unconnected No connection; leave floating.
26 DGND power_in Digital ground; connect to 0 V.
27 DVDD power_in Digital power supply pin; DVDD and IOVDD to DGND are limited to -0.3 V to 7 V.
28 IOVDD power_in Interface power supply pin; IOVDD to DGND is limited to -0.3 V to 7 V.
29 NC unconnected No connection; leave floating.
30 CLR input Active-low DAC register clear input that clears the DAC buffers and latches to the DAC-CLEAR-DATA bits when asserted.
31 SCLK input SPI serial clock input with Schmitt-trigger logic; data are transferred at rates up to 50 MHz.
32 SDIN input SPI serial data input with Schmitt-trigger logic; data are clocked into the input shift register on the falling edge of SCLK.
33 SYNC input Active-low SPI chip select input; data are not clocked into the shift register unless SYNC is low, and SDO is high-impedance when SYNC is high.
34 SDO output Serial data output that is valid on the falling edge of SCLK.
35 AGND power_in Analog ground; connect to 0 V.
36 NC unconnected No connection; leave floating.
37 NC unconnected No connection; leave floating.
38 AGND power_in Analog ground; connect to 0 V.
39 AVDD power_in Positive low-voltage analog power supply; AVDD to AGND is limited to -0.3 V to 7 V.
40 AGND power_in Analog ground; connect to 0 V.
41 AVDD power_in Positive low-voltage analog power supply; AVDD to AGND is limited to -0.3 V to 7 V.
42 AGND power_in Analog ground; connect to 0 V.
43 AGND power_in Analog ground; connect to 0 V.
44 VSS power_in Analog negative power supply; VSS to AGND is limited to -19 V to 0.3 V.
45 VCC power_in Analog positive power supply; VCC to VSS is limited to -0.3 V to 40 V.
46 AGND power_in Analog ground; connect to 0 V.
47 AGND power_in Analog ground; connect to 0 V.
48 NC unconnected No connection; leave floating.
