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 preci-
sion reference with a 20ppm/
°
C max temperature coeffi-
cient. This represents a 4 to 7 times improvement over
similar 3-1/2 digit converters. Existing 7106 and 7107 based
systems may be upgraded without changing external pas-
sive 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 10
12
input impedance. The
differential reference input allows ratiometric measurements
for ohms or bridge transducer measurements. The
15
μ
V
P–P
noise performance guarantees a “rock solid” read-
ing. The auto-zero cycle guarantees a zero display read-
ing with a zero-volts input.
