General Description:
The TC7106A and TC7107A 3-1/2 digit direct display
drive Analog-to-Digital Converters allow existing
TC7106/TC7107 based systems to be upgraded. Each
device has a precision reference with a 20 ppm/°C
maximum temperature coefficient. This represents a 4
to 7 times improvement over similar 3-1/2 digit
converters. Existing TC7106 and TC7107 based
systems may be upgraded without changing external
passive component values. The TC7107A drives
common anode light emitting diode (LED) displays
directly with 8 mA 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 1 pA leakage current and a 1012Ω input
impedance. The differential reference input allows
ratiometric measurements for ohms or bridge
transducer measurements. The 15 μVP–P noise
performance ensures a “rock solid” reading. The autozero
cycle ensures a zero display reading with a zero
volts input.
