What is the largest sensor output that can produce 4V of span (VDD = 5V), without requiring an external circuit?
A. The largest sensor output can be determined when the smallest excitation voltage setting of 1.5V (VDD = 5V) and smallest PGA gain (39x) are applied. The applying equation is: sensor output (mV/V) = Span (V) / [VBDR (V) * PGA-Gain (V/V)] * 1000 The largest possible sensor output is 68mV/V. • Q. Can I use the uncommitted op amp to provide additional gain for the output voltage? A. Yes. • Q. When operating in digital mode and the output MUX is activated for “infinite” output duration, communication is blocked for nine seconds before it is released to accept digital commands. This is unacceptable in a production environment. How can I get around the unnecessary wait after I finish reading the output from a DMM? A. The power to the signal conditioner, VDD, must be cycled. If the supplied KEY and Evaluation Kit (EV kit) software are used, the hard_init (mode = 1) function included in the serial.dll must be executed to cycle power. In this mode (mode = 1) the prepower-cycle contents of the
