AD7782BRUZ

Analog Devices · Analog To Digital Converters (ADCs) · TSSOP-16

AD7782BRUZ from Analog Devices, 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 XTAL1 input Input to the 32.768 kHz crystal oscillator inverter, used with a 32.768 kHz watch crystal.
2 REFIN(+) input Positive reference input that can lie anywhere between VDD and GND +1 V, with a nominal REFIN(+) - REFIN(-) of 2.5 V and operation from 1 V to VDD.
3 REFIN(-) input Negative reference input that can lie anywhere between GND and VDD - 1 V.
4 AIN1(+) input Positive terminal of the fully-differential analog input pair AIN1(+)/AIN1(-), with absolute input voltage limits of GND + 100 mV to VDD - 100 mV.
5 AIN1(-) input Negative terminal of the fully-differential analog input pair AIN1(+)/AIN1(-), with absolute input voltage limits of GND + 100 mV to VDD - 100 mV.
6 AIN2(+) input Positive terminal of the fully-differential analog input pair AIN2(+)/AIN2(-), with absolute input voltage limits of GND + 100 mV to VDD - 100 mV.
7 AIN2(-) input Negative terminal of the fully-differential analog input pair AIN2(+)/AIN2(-), with absolute input voltage limits of GND + 100 mV to VDD - 100 mV.
8 CH1/CH2 input Channel select logic input where CH1/CH2 = 0 selects AIN1(+)/AIN1(-) and CH1/CH2 = 1 selects AIN2(+)/AIN2(-).
9 RANGE input Logic input configuring the PGA input range, where RANGE = 0 gives ±160 mV and RANGE = 1 gives ±2.56 V for a +2.5 V reference.
10 SCLK bidirectional Serial clock that is an output in master mode with one SCLK period equal to one XTAL period, and a Schmitt-triggered input in slave mode.
11 CS input Active-low chip select which, when taken high, aborts the conversion, three-states DOUT and SCLK, and places the part in standby mode.
12 DOUT/RDY output Serial data output and data-ready output that goes low when valid data is available and outputs data on the falling SCLK edge, valid on the rising edge.
13 MODE input Selects the operating mode, with MODE = 0 for master mode and MODE = 1 for slave mode.
14 GND power_in Ground reference point for the AD7782.
15 VDD power_in Supply voltage of 3 V or 5 V nominal, specified for 2.7 V to 3.6 V or 4.75 V to 5.25 V.
16 XTAL2 output Output from the 32.768 kHz crystal oscillator inverter.
