NOTES: (1) CMOS/TTL compatible, i.e., Logic “0” = 0.8V, max, Logic “1” = 2.0V, min for inputs. For digital outputs Logic “0” = 0.4V, max, Logic “1’ = 2.4V, min.
(2) Adjustable to zero. See “Optional External Gain and Offset Adjustment” section. (3) FSR means Full Scale Range. For example, unit connected for
±
10V range
has 20V FSR. (4) Conversion time may be shortened with “Short Cycle” set for lower resolution and with use of Clock Rate Control. See “Optional Conversion Time
Adjustment” section. The Clock Rate Control (pin 23) should be connected to Digital Common for specified conversion time. Short Cycle (pin 32) should be left open
for 16-bit resolution or connected to the n + 1 digital output for n-bit resolution. For example, connect Short Cycle to Bit 15 (pin 15) for 14-bit resolution. For resolutions
less than 16 bits, pin 32 should also be tied to +5V through a 2k
resistor. (5) See Table I. CSB = Complementary Straight Binary, COB = Complementary Offset
Binary, CTC = Complementary Two’s Complement. (6) CTC coding obtained by inverting MSB (pin 1). (7) Adjustable with Clock Rate Control from approximately
933kHz to 1.4MHz.
