General Description
The TC7106A and TC7107A 3-1/2 digit direct display
drive analog-to-digital converters allow existing 7106/
7107 based systems to be upgraded. Each device has
a precision reference with a 20ppm/°C max tempera-
ture coefficient. This represents a 4 to 7 times improve-
ment over similar 3-1/2 digit converters. Existing 7106
and 7107 based systems may be upgraded without
changing external passive component values. The
TC7107A drives common anode light emitting diode
(LED) displays directly with 8mA per segment. A low
cost, high resolution indicating meter requires only a
display,
four
resistors,
and
four
capacitors.The
TC7106A low power drain and 9V battery operation
make it suitable for portable applications.
The TC7106A/TC7107A reduces linearity error to less
than 1 count. Rollover error – the difference in readings
for equal magnitude, but opposite polarity input signals,
is below ±1 count. High impedance differential inputs
offer 1pA leakage current and a 1012
input imped-
ance. The differential reference input allows ratiometric
measurements for ohms or bridge transducer mea-
surements. The 15
VP–P noise performance ensures a
“rock solid” reading. The auto-zero cycle ensures a
zero display reading with a zero volts input.
