6 / 18 page CYRUSTEK CO. ES5108 3 1/2 Digit ADC with serial output Pin Description Pin No. Symbol Type Description 1 VREF- - Low differential reference input connection. 2 VREF+ - High differential reference input connection. 3 DGND - Pull high to V+ all LCD segments will be activated. 4 OSC3 - Crystal oscillator connection.(RC) 5 OSC2 - Crystal oscillator connection.(output) 6 OSC1 - Crystal oscillator connection.(input) 7 INT O Integration status flag. 8 FREQ/VOLT I Frequency counter/voltage measurement select pin. Connecting to V+ will enable the frequency counter, connecting to TEST1 or open will ex- ecute voltage measurement. This pin is internally pull down to TEST1. 9 V+ P Positive supply voltage. 10 CONT/-/MHz O LCD segment drive. (Continuity., polarity, MHz) 11 B4/C4/DP3 O LCD segment drive. (B4, C4, decimal point3) 12 KHz/F3/E3 O LCD segment drive. (KHz, F3, E3) 13 A3/G3/D3 O LCD segment drive. (A3, G3, D3) 14 B3/C3/DP2 O LCD segment drive. (B3, C3, decimal point2) 15 HOLD/F2/E2 O LCD segment drive. (Data Hold, F2, E2) 16 A2/G2/D2 O LCD segment drive. (A2, G2, D2) 17 B2/C2/DP1 O LCD segment drive. (B2, C2, decimal point 1) 18 MAX/F1/E1 O LCD segment drive. (Max, F1, E1) 19 A1/G1/D1 O LCD segment drive. (A1, G1, D1) 20 B1/C1/BAT O LCD segment drive. (B1, C1, low battery) 21 COM1 O LCD common drive#1. 22 COM2 O LCD common drive#2. 23 COM3 O LCD common drive#3. 24 FREQ-in I Frequency counter input pin. 25 DINT O De-Integration status flag. 26 ANNUNC O Square wave output at the LCD backplane frequency, synchronized to COM1. Connecting an LCD segment to ANNUNC pin turns it on; con- necting to backplane turns it off. 27 DP1 I 1st decimal point selection input for voltage measurement, internally pulled-down to TEST1. 28 DP2 I 2nd decimal point selection input for voltage measurement, internally pulled-down to TEST1. 29 DP3 I 3rd decimal point selection input for voltage measurement, internally pulled-down to TEST1. 30 RESET I Reset input pin. Connecting to V+ will cancel both MAX/MIN and Hold functions. 31 MAX I MAX input pin. Pulse to V+ to enable MAX function. 32 HOLD I Hold input pin. Connecting to V+ for hold function. 33 LB O Low battery flag. Pull high if low battery. continued on next page This table is for ES5108L 6 November 23, 2006 |
