DEVICE DESCRIPTION

The AD7175-8 is a highly accurate, high resolution, multiplexed,

8-/16-channel (full/pseudo differential) Σ-Δ ADC. The AD7175-8

has a maximum channel-to-channel scan rate of 50 kSPS (20 µs)

for fully settled data The output data rates range from 5 SPS to

250 kSPS. The device includes integrated analog input and

reference buffers, an integrated precision 2.5 V reference, and

an integrated oscillator.

HARDWARE LINK OPTIONS

See Table 1 for the default link options. By default, the board is

configured to operate from the supplied 9 V ac-to-dc adapter

connected to Connector J4. The 5 V supply required for the

AD7175-8 comes from the on-board low dropout regulator

(LDO). The ADP1720, with a 5 V fixed output voltage, receives

its input voltage from J2 or J4 (depending on the position of LK2)

and generates a 5 V output.

Table 1. Default Link and Solder Link Options

Link Default Option Description

SERIAL INTERFACE

The E VA L -AD7175-8SDZ evaluation board connects to the

Blackfin® ADSP-BF527 on the SDP-B controller board via the

serial peripheral interface (SPI). There are four primary signals,

CS, SCLK, and DIN (all inputs), and one output from the ADC,

DOUT/RDY.

To operate the evaluation board in standalone mode, disconnect

the AD7175-8 serial interface lines from the 120-pin header by

removing the 0 Ω, R9 through R13 links. Use the test points to

connect the signals to an alternative digital capture setup.

POWER SUPPLIES

Power the evaluation board from the ac-to-dc adapter

connected to J4, or from an external bench top supply applied

to J3 or J5. Linear LDOs generate the required voltages from the

applied input voltage (VIN) rail when using J3 or J4. Use J5 to

bypass the on-board regulators. The regulators used are the 5 V

fixed output voltage and 2.5 V adjustable output voltage

ADP1720 devices, which supply the AVDD1 and AVDD2 rails

to the ADC; the ADP1720 (3.3 V) supplies the IOVDD rail. Use

the ADP7104 (5 V) to supply 5 V for the SDP-B controller

board. Each supply is decoupled where it enters the board and

again at each device. Table 3 shows the various power supply

configurations available, including split supply operation.
