ADS114S08IPBSR

Texas Instruments · Analog To Digital Converters (ADC) · TQFP-32(5x5)

ADS114S08IPBSR from Texas Instruments, in a TQFP-32(5x5). 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 AINCOM input Common analog input for single-ended measurements.
2 AIN5 input Analog input 5.
3 AIN4 input Analog input 4.
4 AIN3 input Analog input 3.
5 AIN2 input Analog input 2.
6 AIN1 input Analog input 1.
7 AIN0 input Analog input 0.
8 START/SYNC input Start conversion; rising edge initiates new conversion in sync mode.
9 CS input Chip select; active low.
10 DIN input Serial data input; data latched on SCLK falling edge.
11 SCLK input Serial clock input; input latched on falling edge, output updated on rising edge.
12 DOUT/DRDY tri_state Serial data output and data ready indicator; active low; high-impedance when CS is high.
13 DRDY output Data ready output; active low.
14 DGND power_in Digital ground.
15 IOVDD power_in Digital I/O power supply; absolute maximum 5.5V.
16 DVDD power_in Digital core power supply; 2.7V to 3.6V operating range.
17 CLK input External clock input; tie to DGND to use internal 4.096 MHz oscillator.
18 RESET input Reset; active low.
19 GPIO3/AIN11 bidirectional Configurable as general-purpose I/O or analog input 11 on ADS114S08.
20 GPIO2/AIN10 bidirectional Configurable as general-purpose I/O or analog input 10 on ADS114S08.
21 GPIO1/AIN9 bidirectional Configurable as general-purpose I/O or analog input 9 on ADS114S08.
22 GPIO0/AIN8 bidirectional Configurable as general-purpose I/O or analog input 8 on ADS114S08.
23 REFOUT output Positive voltage reference output; internal 2.5V reference.
24 REFCOM output Reference common output; connect to AVSS.
25 NC unconnected No connect; leave floating or connect to AVSS.
26 AVDD power_in Positive analog power supply; 2.7V to 5.25V.
27 AVSS power_in Negative analog power supply.
28 AVSS-SW power_in Negative analog power supply with low-side switch; connect to AVSS.
29 REFN0 input Negative external voltage reference input 0.
30 REFP0 input Positive external voltage reference input 0.
31 REFN1/AIN7 input Negative reference input 1 or analog input 7 on ADS114S08.
32 REFP1/AIN6 input Positive reference input 1 or analog input 6 on ADS114S08.

Key specifications

Parameter Value
Manufacturer Texas Instruments
Package TQFP-32(5x5)
Category Data Acquisition
Pins 32

CAD (KiCad official)

  • Symbol: ADS114S08IPBSR
  • Footprint: Package_QFP:TQFP-32_5x5mm_P0.5mm
  • 3D model: TQFP-32(5x5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.1 mm nominal TQFP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: ads114s08ipbsr-etched.step / ads114s08ipbsr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ads114s08ipbsr.step / ads114s08ipbsr.glb are the bare package body.
