ADS8344N

Texas Instruments · Analog To Digital Converters (ADC) · SSOP-20-208mil

ADS8344N from Texas Instruments, in a SSOP-20-208mil. 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 CH0 input Analog input channel 0 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
2 CH1 input Analog input channel 1 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
3 CH2 input Analog input channel 2 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
4 CH3 input Analog input channel 3 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
5 CH4 input Analog input channel 4 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
6 CH5 input Analog input channel 5 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
7 CH6 input Analog input channel 6 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
8 CH7 input Analog input channel 7 for single-ended or differential conversion; the datasheet gives an absolute positive-input range of -0.2 V to +VCC + 0.2 V.
9 COM passive Ground reference for the analog inputs that sets the zero-code voltage in single-ended mode; connect to ground or a ground reference point.
10 SHDN input Shutdown input; when LOW the device enters a very low-power shutdown mode.
11 VREF power_in Voltage reference input; the reference can be varied between 500 mV and VCC, giving an input span of 0 V to VREF.
12 +VCC power_in Power supply, 2.7 V to 5 V.
13 GND power_in Ground.
14 GND power_in Ground.
15 DOUT tri_state Serial data output; data is shifted on the falling edge of DCLK, and the output is high impedance when CS is HIGH.
16 BUSY tri_state Busy output; goes LOW while the DIN control bits are being read and while the device is converting, and is high impedance when CS is HIGH.
17 DIN input Serial data input; when CS is LOW, data is latched on the rising edge of DCLK.
18 CS input Active-LOW chip select; data is not clocked into DIN unless CS is LOW, and DOUT is high impedance when CS is HIGH.
19 DCLK input External clock input; the clock speed sets the conversion rate by the equation fDCLK = 24 • fSAMPLE.
20 +VCC power_in Power supply; the device is specified for a single supply of 2.7 V to 5 V.
