ADS1271IBPWR

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-16-175mil

ADS1271IBPWR from Texas Instruments, in a TSSOP-16-175mil. 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	AINP	input	Positive analog input; input impedance 16.4kΩ in High-Speed/High-Resolution modes or 32.8kΩ in Low-Power mode.
2	AINN	input	Negative analog input; input impedance 16.4kΩ in High-Speed/High-Resolution modes or 32.8kΩ in Low-Power mode.
3	AGND	power_in	Analog ground.
4	AVDD	power_in	Analog supply voltage, range 4.75V to 5.25V (nominal 5V).
5	MODE	input	Mode selection input: 0=High-Speed (105kSPS), float=High-Resolution (109dB SNR), 1=Low-Power (35mW).
6	FORMAT	input	Interface format selection: 0=SPI, float=Modulator output (ADS1271B only), 1=Frame-Sync.
7	SYNC/PDWN	input	Synchronization (pulse low) or power-down (hold low ≥219 CLK periods) control, active low.
8	DIN	input	Serial data input for daisy-chaining; latched on falling edge of SCLK.
9	DOUT	output	Serial data output (ADC or modulator output); shifts MSB-first on falling edge of SCLK.
10	DRDY/FSYNC	bidirectional	Data ready output in SPI mode or frame-sync input in Frame-Sync mode; mode-dependent function.
11	SCLK	input	Serial clock input for data retrieval in SPI and Frame-Sync modes; becomes modulator clock output in modulator mode.
12	CLK	input	Master clock input, operating range 0.1MHz to 27MHz; crystal oscillator recommended.
13	DVDD	power_in	Digital supply voltage, range 1.65V to 3.6V (1.8V recommended).
14	DGND	power_in	Digital ground.
15	VREFN	input	Negative reference input; valid operating range depends on device grade (ADS1271 or ADS1271B).
16	VREFP	input	Positive reference input; valid operating range depends on device grade (ADS1271 or ADS1271B).
