PIN DESCRIPTION

Refer to figure 2.
EMP Symbol Description
1 V Voltage reference supply pin, 2.5 V nominal (3.0 V maximum)
Ref
2 DA Digital-to-Analog 1, voltage output. Output between 0.0 V and V
1
3 Sign Sign 1, TTL/CMOS level. To be connected directly to NJM377x phase input. Databit D7 is transfered non
1
inverted from NJU39612 data input.
4 V Voltage Drain-Drain, logic supply voltage. Normally +5 V.
DD
5 WR Write, TTL/CMOS level, input for writing to internal registers. Data is clocked into flip flops on positive
edge.
6 D7 Data 7, TTL/CMOS level, input to set data bit 7 in data word.
7 D6 Data 6, TTL/CMOS level, input to set data bit 6 in data word.
8 D5 Data 5, TTL/CMOS level, input to set data bit 5 in data word.
9 D4 Data 4, TTL/CMOS level, input to set data bit 4 in data word.
10 D3 Data 3, TTL/CMOS level, input to set data bit 3 in data word.
11 D2 Data 2, TTL/CMOS level, input to set data bit 2 in data word.
12 D1 Data 1, TTL/CMOS level, input to set data bit 1 in data word.
13 D0 Data 0, TTL/CMOS level, input to set data bit 0 in data word.
14 A0 Address 0, TTL/CMOS level, input to select data transfer, A0 selects between cannel 1 (A0 = LOW) and
channel 2 (A0 = HIGH).
15 NC Not connected
16 CS Chip Select, TTL/CMOS level, input to select chip and activate data transfer from data inputs. LOW level
= chip is selected.
17 V Voltage Source-Source. Ground pin, 0 V reference for all signals and measurements unless otherwise
SS
noted.
18 Sign Sign 2. TTL/CMOS level. To be connected directly to NJM377x phase input. Data bit D7 is transfered
2
non-inverted from NJU39612 data input.
19 DA Digital-to-Analog 2, voltage output. Output between 0.0 V and V
2
20 Reset Reset, digital input resetting internal registers. HIGH level = Reset, V
