description (continued)
An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the
application. Two different conversion modes can be selected. In single conversion mode, a single and
simultaneous conversion of up to four inputs can be initiated by using the single conversion start signal
(CONVST). The conversion clock in single conversion mode is generated internally using a clock oscillator
circuit. In continuous conversion mode, an external clock signal is applied to the CONV_CLK input of the
THS1206. The internal clock oscillator is switched off in continuous conversion mode.
