ICL7107 Datasheet | Estek Electronics

ICL7106/7107 .. Description The ICL7106 and ICL7107 are high performance,low power 3 1 / 2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display (LCD) and includes a multiplexed backplane drive, the ICL7107 will directly drive an instrument size light emitting diode (LED) display. The ICL7106 and ICL7107 bring together a bination of high accuracy, versatility, and true economy. True differential inputs and reference are useful in all systems, but give the designer an unmon advantage when measuring load cells, strain gauges and other bridge type transducers. Finally he true economy of single power Supply operation ( ICL7106 ), enables a high performance panel meter to be built with the addition of only 10 passive display. ponents and a ICL7106, ICL7107 TOP VIEW Features - Guaranteed Zero Reading for 0V input on All Scales - True Polarity at Zero for Precise Null Detection (1’ s) V+ D1 C1 B1 A1 F1 G1 E1 D2 C2 (10’ s) B2 A2 F2 E2 D3 (100’ s) B3 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 40 OSC 1 39 OSC 2 38 OSC 3 37 TEST 36 REF HI 35 REF LO 34 CREF+ CREF33 MON 32 IN HI 31 IN LO 30 A-Z 29 BUFF 28 INT 27 Vs) 26 G2 (10’ 25 C3 24 A3 23 22 G3 21 BP/GND - True Differential input and Reference, Direct Display - Drive - LCD ICL7106 - LED ICL7107 - Low Noise-Less Than 15 u Vp-p - On Chip Clock and Reference - Low Power Dissipation Typically Less Than 10m W - No Additional Active Circuits Required - New Small Outline Surface Mount Package Available F3 E3 (1000) AB4 (MINUS)...
