The serial interface consists of bit clock, data, and latch enable

inputs. The twos-complement data word is clocked MSB first

on falling clock edges into the serial-to-parallel converter, con-

sistent with the serial protocols of popular DSP processors. The

input clock can support data transfers up to 12.5 MHz. The

falling edge of latch enable updates the internal DAC input reg-

ister at the sample rate with the sixteen bits most recently

clocked into the serial input register.

PRODUCT DESCRIPTION

The AD766 16-bit DSP DACPORT provides a direct, three-

wire interface to the serial ports of popular DSP processors, in-

cluding the ADSP-2101, TMS320CXX, and DSP56001. No

additional “glue logic” is required. The AD766 is also com-

plete, offering on-chip serial-to-parallel input format conver-

sion, a 16-bit current-steering DAC, voltage reference, and a

voltage output op amp. The AD766 is fabricated in Analog

Devices’ BiMOS II mixed-signal process which provides bipolar

transistors, MOS transistors, and thin-film resistors for preci-

sion analog circuits in addition to CMOS devices for logic.

The AD766 operates over a ±5 V to ±12 V power supply range.

The digital supplies, +V_Land –V_L, can be separated from the

analog signal supplies, +V_Sand –V_S, for reduced digital

crosstalk. Separate analog and digital ground pins are also pro-

vided. An internal bandgap reference provides a precision volt-

age source to the output amp that is stable over temperature and

time.

The design and layout of the AD766 have been optimized for ac

performance and are responsible for its guaranteed and tested

94 dB signal-to-noise ratio to 20 kHz and 79 dB SNR to

250 kHz. Laser-trimming the AD766’s silicon chromium thin-

film resistors reduces total harmonic distortion below –81 dB

(at 1 kHz), a specification also production tested. An optional

linearity trim pin allows elimination of midscale differential

linearity error for even lower THD with small signals.

Power dissipation is typically 120 mW with ±5 V supplies and

300 mW with ±12 V. The AD766 is available in commercial

(0°C to +70°C), industrial (–40°C to +85°C), and military

(–55°C to +125°C) grades. Commercial and industrial grade

parts are available in a 16-pin plastic DIP; military parts pro-

cessed to MIL-STD-883B are packaged in a 16-pin ceramic

DIP. See Analog Devices’ Military Products Databook or current

military data sheet for specifications for the military version.

The AD766’s output amplifier provides a ±3 V signal with a

high slew rate, small glitch, and fast settling. The output ampli-

fier is short circuit protected and can withstand indefinite shorts

to ground.
