AMC7823IRTAR

Texas Instruments · ADCs/DACs - Special Purpose · WQFN-40(6x6)

AMC7823IRTAR from Texas Instruments, in a WQFN-40(6x6). 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 GALR output Global analog input out-of-range alarm; this pin goes low (active) when one or more of the first four accessed analog inputs is out of preset range.
2 DAV output Data available indicator; in auto-mode a 2μs active-low pulse appears on this pin when a conversion cycle finishes, and it stays high when deactivated.
3 ELDAC input External DAC synchronous load trigger; DACs selected for external synchronous load update simultaneously on the rising edge of ELDAC.
4 ISET_RESISTOR passive The resistor connected from the analog supply to this pin sets the current output from PRECISION_I_OUTPUT; the voltage across the set resistor should be limited to about 0.5V.
5 PRECISION_I_OUTPUT output Current output to drive a thermistor, with output current range 0.01 mA to 10 mA and compliance voltage of about 2V.
6 DAC 0_OUT output Output of DAC 0, programmable from 0 to VREF or 0 to 2 × VREF.
7 DAC 1_OUT output Output of DAC 1, programmable from 0 to VREF or 0 to 2 × VREF.
8 DAC 2_OUT output Output of DAC 2, programmable from 0 to VREF or 0 to 2 × VREF.
9 DAC 3_OUT output Output of DAC 3, programmable from 0 to VREF or 0 to 2 × VREF.
10 SGND power_in Analog input signal ground; must connect to the ground of the analog input source to minimize digital noise.
11 CH0 passive Analog input channel 0, with input range 0 to 2 × VREF.
12 CH1 passive Analog input channel 1, with input range 0 to 2 × VREF.
13 CH2 passive Analog input channel 2, with input range 0 to 2 × VREF.
14 CH3 passive Analog input channel 3, with input range 0 to 2 × VREF.
15 AGND power_in Analog ground.
16 AVDD power_in Analog power supply, +3V to +5V; must be the same value as DVDD.
17 CH4 passive Analog input channel 4, with input range 0 to 2 × VREF.
18 CH5 passive Analog input channel 5, with input range 0 to 2 × VREF.
19 CH6 passive Analog input channel 6, with input range 0 to 2 × VREF.
20 CH7 passive Analog input channel 7, with input range 0 to 2 × VREF.
21 EXT_REF_IN bidirectional External reference input; when internal reference is selected it works as the internal reference output with 10kΩ output impedance.
22 DAC 4_OUT output Output of DAC 4, programmable from 0 to VREF or 0 to 2 × VREF.
23 DAC 5_OUT output Output of DAC 5, programmable from 0 to VREF or 0 to 2 × VREF.
24 DAC 6_OUT output Output of DAC 6, programmable from 0 to VREF or 0 to 2 × VREF.
25 DAC 7_OUT output Output of DAC 7, programmable from 0 to VREF or 0 to 2 × VREF.
26 RESET input Reset input; a logic low on this pin causes the part to perform a hardware reset.
27 GPIO-0/ALR0 bidirectional Multiple-function I/O pin that works as digital I/O or as the ALR pin of the first analog input; an external pull-up is required when used as output.
28 GPIO-1/ALR1 bidirectional Multiple-function I/O pin that works as digital I/O or as the ALR pin of the second analog input; an external pull-up is required when used as output.
29 GPIO-2/ALR2 bidirectional Multiple-function I/O pin that works as digital I/O or as the ALR pin of the third analog input; an external pull-up is required when used as output.
30 GPIO-3/ALR3 bidirectional Multiple-function I/O pin that works as digital I/O or as the ALR pin of the fourth analog input; an external pull-up is required when used as output.
31 CONVERT input External conversion trigger; the rising edge starts ADC sampling and conversion when external trigger mode is selected.
32 SCLK input Serial clock input for the SPI interface.
33 MOSI input Master out, slave in; digital data input for the serial interface.
34 MISO output Master in, slave out; digital data output for the serial interface, high impedance when SS is high.
35 SS input Active-low slave select input; data is not clocked into MOSI unless SS is low.
36 BVDD power_in Interface power supply; connect to 3V for 3V logic or 5V for 5V logic, and it must not exceed AVDD or DVDD.
37 DVDD power_in Digital power supply, +3V to +5V; must be the same value as AVDD.
38 DGND power_in Digital ground.
39 GPIO-4 bidirectional Dedicated general-purpose bidirectional digital I/O pin.
40 GPIO-5 bidirectional Dedicated general-purpose bidirectional digital I/O pin.
41 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
