Hi,The 1540 is in the '88 book:
1 data input 2 latch enable input 3 voltage reference 4 pos supply 5 freq compensation 6 gnd 7 neg supply 8&9 oscillator capacitor 10 voltage reference 11 neg supply 12&&14 decoupling binary weighted current sources 15&&17 current ref sources 18&&21 decoupling binary weighted current sources 22 analogue out 23&&25 decoupling binary weighted current sources 26&27 voltage ref 28 clock inapplication circuit:
1/28/2: dig in, 4 +5, 6 gnd, 7 -5, 3 with 10nf to 7, 11 -17v, 10 with 2k7 to 11, 820pf 1% between 8&9, 22 iout, 15 with 620 0.5% to 16, 17 with 82 0.5% to 16, 16 also with 1.5nf to gnd, 12 470nf to gnd, 13 220nf to gnd, 14 100nf to gnd, 18 47nf to gnd, 19 22nf to gnd, 21 10nf to gnd - also 23,24 and 25.no designation are resistors, e.g. 82 means 82 ohms. 2k7 is 2700 ohm.
hope this helps a bit, don't have a scanner....
Greetings,
Guido
