1 / 10 page 03/07/21 1 ES5117 3 1/2 DVM with LED Display and Hold Features • Guaranteed zero reading with zero input • Low input leakage current (1pA typical) • Internal reference with low temperature drift ( 60ppm/℃ typically) • Low noise (15uVp-p typical) • Direct LED display driver • Differential input and voltage reference • Precise null detection with true polarity at zero • Internal clock circuit • No additional active circuits required • Display Hold Description The ES5117 is a monolithic CMOS 3 1/2 digit LED display A/D converter with Display Hold function. It contains the internal clock, voltage reference, seven- segment decoder and LED display driver. The improved internal zener reference voltage circuit gives the analog common a small temperature coefficient of 60ppm/℃ typically. The high accuracy characteristics of the ES5117 perform very low linearity error and rollover error. The high input impedance (>1012Ω) and low input leakage current (1pA typical) give the ES5117 a good application in the field of high impedance circuit measurement. The differential input and reference are suitable for measuring bridge transducer or ohms by using ratio-metric method. The dual slope conversion technique makes the ES5117 a good normal and common mode rejection ratio. With a suitable oscillator frequency, the ES5117 has a high rejection of 50Hz, 60Hz and 400Hz line frequency noise. With single power supply, a few passive components and a LED display, ES5117 can be built as high performance panel meter. Application Digital panel meters |
