TC9400 converter operates principal charge balancing. operation TC9400 easily understood referring Figure 3-1. input voltage (VIN) converted current (IIN) input resistor. This current then converted charge integrating capacitor shows linearly decreasing voltage output amp. lower limit output swing threshold detector, which causes reference voltage applied reference capacitor time period long enough charge capacitor reference voltage. This action reduces charge integrating capacitor fixed amount CREF VREF), causing output step finite amount. charging period, CREF shorted out. This dissipates charge stored reference capacitor, that when output again crosses zero, system ready recycle. this manner, continued discharging integrating capacitor input balanced fixed charges from refer-
ence voltage. input voltage increased, number reference pulses required maintain balance increases, which causes output frequency also increase. Since each charge increment fixed, increase frequency with voltage linear. addition, accuracy output pulse width does directly affect linearity V/F. pulse must simply long enough full charge transfer take place. TC9400 contains "self-start" circuit ensure converter always operates properly when power first applied. event that, during power-on, output below threshold CREF already charged, positive voltage step will occur. output will continue decrease until crosses -3.0V threshold "self-start" comparator. When this happens, internal resistor connected input, which forces output positive until TC9400 normal Operating mode. TC9400 utilizes low-power CMOS processing input bias offset currents, with very power dissipation. open drain N-channel output FETs provide high voltage high current sink capability.

Voltage-to-Time Measurements
TC9400 output measured time domain well frequency domain. Some microcomputers, example, have extensive timing capability, limited counter capability. Also, response time time domain measurement only period between output pulses, while frequency measurement must accumulate pulses during entire counter time-base period. Time measurements made from either TC9400's PULSE FREQ output, from FREQ/2 output. FREQ/2 output changes state rising edge PULSE FREQ OUT, FREQ/2 symmetrical square wave one-half pulse output frequency. Timing measurements can, therefore, made between successive PULSE FREQ pulses, while FREQ/2 high low).
