3 / 12 page 07/03/01 3 ES5129 4-1/2 digit with LCD 9 F2, E2, DP2 O Output to LCD segment. 10 B3, C3, MINUS O Output to LCD segment. 11 A3, G3, D3 O Output to LCD segment. 12 F3, E3, DP3 O Output to LCD segment. 13 B4, C4, BC5 O Output to LCD segment. 14 A4, G4, D4 O Output to LCD segment. 15 F4, E4, DP4 O Output to LCD segment. 16 BP3 O LCD backplane signal 17 BP2 O LCD backplane signal 18 BP1 O LCD backplane signal 19 VDISP P Negative supply for display drivers. 20 DP4/OR I/O Input: Turns on most significant decimal point when HI. Output: Pulled HI when result count exceeds ±19,999. 21 DP3/UR I/O Input: Turn on the 2nd significant decimal point when HI. Output: Pulled HI when result count is less than ±1,000. 22 LATCH/HOLD I/O Input: when floating, ES5129 operates in the free-run mode. When pulled high, the last display reading is held. When pulled LO, the result counter contents are shown incrementing during the de-integrate phase of cycle. Output: Negative going edge occurs when the data latche are upgraded. Can be used as a converter status signal. 23 V- P Negative power supply terminal 24 V+ P Positive power supply terminal 25 CAZ I/O Integrator amplifier input 26 CINT I/O Integrator amplifier output 27 CONTINUITY I/O Input: when LO, continuity flag on the display is off. When HI, continuity flag is on. Output: HI when voltage between inputs is less than +200mV. LO when voltage between inputs is more than +200mV. 28 COMMON O Set common-mode voltage of 3.2V below V+. 29 CREF+ I/O Positive connection to external reference capacitor 30 CREF- I/O Negative connection to external reference capacitor 31 BUFFER O Buffer amplifier output 32 IN_LO I Negative input voltage terminal 33 IN_HI I Positive input voltage terminal 34 REF_HI I Positive reference voltage terminal 35 REF_LO I Negative reference voltage terminal 36 DGND O Ground reference for digital section 37 RANGE I Pulled HIGH externally for 2V scale. 38 DP2 I When HI, decimal point 2 will be on. 39 DP1 I When HI, decimal point 1 will be on. 40 OSC2 I/O Output of first clock inverter. Input of second clock inverter. |
