DESCRIPTION
Channel A Trim Reference Out. 10 F Tantalum to
AGND. Voltage on this pin is approximately 2.75V.
Channel A Analog In.
Channel A MSB Adjust In.
Channel A VOS Adjust In.
–5V Analog Power.
+5V Analog Power.
Digital Ground.
Digital Ground.
+5V Digital Power.
Conversion Clock In.
Conversion Clock Out. Can drive multiple DSP101/
DSP102s to synchronize conversion.
Select Synch Format In. If HIGH, SYNC will be
active High. If LOW, SYNC will be active Low. See
timing diagram (Figure 1).
Oscillator Point 1 Input / External Clock In. If using
external clock, drive with 74HC logic levels.
Connect to DGND if not used.
Oscillator Point 2 Output. Provides drive for crystal
oscillator. Make no electrical connection if using
external clock.
Data Synchronization Out. Active High when SSF
is HIGH; active Low when SSF is LOW.
Data Transfer Clock In.
Channel B Serial Data Out. MSB first, Binary
Two’s Complement format.
Channel A User Tag In. Data clocked into this pin
is appended to the conversion results of SOUTA.
See timing diagram (Figure 1).
Channel B User Tag In. Data clocked into this pin
is appended to the conversion results of SOUTB.
See timing diagram (Figure 1).
Channel A Serial Data Out. MSB first, Binary
Two’s Complement format. If CASC is HIGH, 32
bits of data output, with first 16 bits being Channel
A data.
Convert Command In. Falling edge puts converter
into hold state, initiates conversion, and transmits
previous conversion results to DSP IC with
appropriate SYNC pulse.
Select Cascade Mode In. If HIGH, DSP102
transmits a 32-bit word on SOUTA, with the first 16
bits being data on Channel A. If LOW, DSP102
transmits data for both channels simultaneously.
Channel B VOS Adjust In.
Channel B MSB Adjust In.
Channel B Analog In.
Channel B Trim Reference Out. 10 F Tantalum to
AGND. Voltage on this pin is approximately 2.75V.
Reference Bypass. 0.1 F Ceramic to AGND.
Voltage on this pin is approximately 3.8V.
Analog Ground.
