AD7924BRUZ-REEL7

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

AD7924BRUZ-REEL7 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 SCLK input Serial clock logic input that accesses the device data and also acts as the clock source for the conversion process.
2 DIN input Serial data logic input that loads the control register on SCLK falling edges, with the first 12 clocks after CS falls loading the register when the WRITE bit is 1.
3 CS input Active-low logic chip select that starts a conversion on its falling edge and enables serial data frame transfer.
4 AGND power_in Analog ground reference for all analog circuitry; all AGND pins should be connected together and returned to the AGND plane.
5 AVDD power_in Analog supply input with a range of 2.7 V to 5.25 V, where the 0 V to 2 × REFIN input range requires 4.75 V to 5.25 V.
6 AVDD power_in Analog supply input with a range of 2.7 V to 5.25 V, where the 0 V to 2 × REFIN input range requires 4.75 V to 5.25 V.
7 REFIN input External reference voltage input that must be driven with 2.5 V ±1% for rated performance and should be decoupled with at least 0.1 µF.
8 AGND power_in Analog ground reference for all analog circuitry; all AGND pins should be connected together and returned to the AGND plane.
9 VIN3 input Single-ended analog input channel 3, multiplexed to the sample-and-hold with a 0 V to REFIN or 0 V to 2 × REFIN range; unused channels should be tied to AGND.
10 VIN2 input Single-ended analog input channel 2, multiplexed to the sample-and-hold with a 0 V to REFIN or 0 V to 2 × REFIN range; unused channels should be tied to AGND.
11 VIN1 input Single-ended analog input channel 1, multiplexed to the sample-and-hold with a 0 V to REFIN or 0 V to 2 × REFIN range; unused channels should be tied to AGND.
12 VIN0 input Single-ended analog input channel 0, multiplexed to the sample-and-hold with a 0 V to REFIN or 0 V to 2 × REFIN range; unused channels should be tied to AGND.
13 AGND power_in Analog ground reference for all analog circuitry; all AGND pins should be connected together and returned to the AGND plane.
14 DOUT tri_state Serial data output that delivers the conversion result MSB first on SCLK falling edges and returns to three-state when the transfer is complete.
15 VDRIVE power_in Logic interface supply input that sets the serial interface voltage and must not exceed AVDD by more than 0.3 V.
16 AGND power_in Analog ground reference for all analog circuitry; all AGND pins should be connected together and returned to the AGND plane.
