Description
Voltage reference supply pin, 2.5 V nominal (3.0 V maximum)
Digital-to-Analog 1, voltage output. Output between 0.0 V and V
Sign 1, TTL/CMOS level. To be connected directly to NJM3771 Phase input.
Databit D7 is transfered non inverted from NJU39610 data input.
Current Decay 1, TTL/CMOS level. The signal is automatically generated when
decay level is programmed. LOW level = fast current decay.
Voltage Drain-Drain, logic supply voltage. Normally +5 V.
Write, TTL/CMOS level, input for writing to internal registers.
Data is clocked into flip flops on positive edge.
Data 7, TTL/CMOS level, input to set data bit 7 in data word.
Data 6, TTL/CMOS level, input to set data bit 6 in data word.
Data 5, TTL/CMOS level, input to set data bit 5 in data word.
Data 4, TTL/CMOS level, input to set data bit 4 in data word.
Data 3, TTL/CMOS level, input to set data bit 3 in data word.
Data 2, TTL/CMOS level, input to set data bit 2 in data word.
Data 1, TTL/CMOS level, input to set data bit 1 in data word.
Data 0, TTL/CMOS level, input to set data bit 0 in data word.
Address 0, TTL/CMOS level, input to select data transfer,
A0 selects between cannel 1 (A0 = LOW) and channel 2 (A0 = HIGH).
Address 1, TTL/CMOS level, input to select data transfer. A1 selects between normal
D/A register programming (A1 = LOW) and decay level register programming (A1 = HIGH).
Chip Select, TTL/CMOS level, input to select chip and activate data transfer
from data inputs. LOW level = chip is selected.
Voltage Source-Source. Ground pin, 0 V reference for all signals and
measurements unless otherwise noted.
Current Decay 2, TTL/CMOS level. The signal is automatically generated
when decay level is programmed. LOW level = fast current decay .
Sign 2. TTL/CMOS level. To be connected directly to NJM3771 sign input.
Data bit D7 is transfered non-inverted from NJU39610 data input.
Digital-to-Analog 2, voltage output. Output between 0.0 V and V
Reset, digital input resetting internal registers.
HIGH level = Reset, V
