AD7328BRUZ-REEL7

Analog Devices · Analog To Digital Converters (ADCs) · TSSOP-20

AD7328BRUZ-REEL7 from Analog Devices, in a TSSOP-20. 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 CS input Active-low chip select that initiates conversions on the AD7328 and frames the serial data transfer.
2 DIN input Data input for writing to the on-chip registers, clocked into the register on the falling edge of SCLK.
3 DGND power_in Digital ground reference for all digital circuitry; DGND and AGND should ideally be at the same potential and must not be more than 0.3 V apart, even transiently.
4 AGND power_in Analog ground reference for all analog circuitry; analog inputs and any external reference must be referred to AGND, and AGND must not be more than 0.3 V from DGND, even transiently.
5 REFIN/OUT bidirectional Reference input/output: the internal 2.5 V reference appears here and requires a 680 nF capacitor, or an external reference can be applied if the internal reference is disabled; external reference mode is the power-up default.
6 VSS power_in Negative power supply voltage for the analog input section.
7 VIN0 passive Analog input channel 0 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
8 VIN1 passive Analog input channel 1 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
9 VIN4 passive Analog input channel 4 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
10 VIN5 passive Analog input channel 5 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
11 VIN7 passive Analog input channel 7 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
12 VIN6 passive Analog input channel 6 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
13 VIN3 passive Analog input channel 3 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
14 VIN2 passive Analog input channel 2 into the on-chip track-and-hold, selected via ADD2-ADD0 and configurable with the mode bits and per-channel input range registers (±10 V, ±5 V, ±2.5 V, 0 V to +10 V with a +2.5 V reference).
15 VDD power_in Positive power supply voltage for the analog input section.
16 VCC power_in Analog supply for the ADC core, rated 2.7 V to 5.25 V with specifications applying from 4.75 V to 5.25 V, and should be decoupled to AGND.
17 VDRIVE power_in Logic power supply input that sets the interface operating voltage; it should be decoupled to DGND and must not exceed VCC by more than 0.3 V.
18 DOUT output Serial data output that clocks out on the falling edge of SCLK, requiring 16 SCLKs to access the MSB-first data stream of three channel ID bits, a sign bit and 12 conversion bits.
19 DGND power_in Digital ground pin, internally common with DGND pin 3, referenced to AGND within 0.3 V.
20 SCLK input Serial clock logic input used to access data from the AD7328 and as the clock source for the conversion process.
