ADS1242IPWR

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

ADS1242IPWR from Texas Instruments, in a TSSOP-16. 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 VDD power_in Power supply input rated for 2.7V to 5.25V operation.
2 XIN input Clock input for external oscillator, maximum 5 MHz.
3 XOUT output Clock output for connection to external crystal or ceramic resonator.
4 PDWN input Active LOW power down control that disables analog and digital circuits when LOW.
5 VREF+ power_in Positive differential reference input (0V to VDD); differential voltage (VREF+)−(VREF−) ranges 0.1V to 1.30V (RANGE=0) or 2.6V (RANGE=1).
6 VREF- power_in Negative differential reference input (0V to VDD); differential voltage (VREF+)−(VREF−) ranges 0.1V to 1.30V (RANGE=0) or 2.6V (RANGE=1).
7 AIN0/D0 bidirectional Analog input channel 0 or digital I/O 0, input range GND+0.05V to VDD−1.5V (buffer enabled).
8 AIN1/D1 bidirectional Analog input channel 1 or digital I/O 1, input range GND+0.05V to VDD−1.5V (buffer enabled).
9 AIN2/D2 bidirectional Analog input channel 2 or digital I/O 2, input range GND+0.05V to VDD−1.5V (buffer enabled).
10 AIN3/D3 bidirectional Analog input channel 3 or digital I/O 3, input range GND+0.05V to VDD−1.5V (buffer enabled).
11 GND power_in Ground reference.
12 CS input Active LOW chip select input for SPI serial interface.
13 DIN input Serial data input with Schmitt trigger, 50ns setup time required before SCLK edge.
14 DOUT tri_state Serial data output with tri-state (high impedance) when CS is HIGH, valid 50ns after SCLK edge.
15 SCLK input Serial clock input with Schmitt trigger, minimum period 4 tOSC or 3 DRDY periods.
16 DRDY output Active LOW data ready output indicating when a new conversion result is available.
