AD7689BCPZRL7

Analog Devices · Analog To Digital Converters (ADC) · LFCSP-20(4x4)

AD7689BCPZRL7 from Analog Devices, in a LFCSP-20(4x4). 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; the datasheet specifies operation from 2.3 V to 5.5 V.
2	REF	bidirectional	Reference buffer pin for the internal or external reference, with the datasheet giving a 0.5 V to VDD range and a 10 µF decoupling capacitor to GND when the internal reference is used.
3	REFIN	bidirectional	External reference input, with the block diagram specifying a range of 0.5 V to VDD − 0.5 V.
4	GND	power_in	Ground reference for the device.
5	GND	power_in	Ground reference for the device.
6	IN4	input	Analog input channel 4, with the multiplexed input range stated as 0 V to VREF/2.
7	IN5	input	Analog input channel 5, with the multiplexed input range stated as 0 V to VREF/2.
8	IN6	input	Analog input channel 6, with the multiplexed input range stated as 0 V to VREF/2.
9	IN7	input	Analog input channel 7, with the multiplexed input range stated as 0 V to VREF/2.
10	COM	input	Common analog input pin shared by the channel multiplexer as the reference point for the single-ended channels.
11	CNV	input	Conversion start input, where a conversion is initiated on the CNV edge.
12	DIN	input	Serial data input used to configure the ADC over the SPI-compatible interface.
13	SCK	input	Serial clock input for the SPI-compatible interface.
14	SDO	output	Serial data output from which the conversion result is shifted out, MSB first.
15	VIO	power_in	Interface digital supply, specified from 1.8 V to 5.5 V, which sets the serial interface logic levels.
16	IN0	input	Analog input channel 0, with the multiplexed input range stated as 0 V to VREF/2.
17	IN1	input	Analog input channel 1, with the multiplexed input range stated as 0 V to VREF/2.
18	IN2	input	Analog input channel 2, with the multiplexed input range stated as 0 V to VREF/2.
19	IN3	input	Analog input channel 3, with the multiplexed input range stated as 0 V to VREF/2.
20	VDD	power_in	Second power supply pin, tied to the same 2.3 V to 5.5 V supply as pin 1.
21	EPAD	unconnected	Exposed pad is not connected internally; solder it to the system ground plane for solder-joint reliability.
