1MHz Pulse Width Modulator 8 Second to 8.5 Minute Low Frequency Clock (Intervalometer for Time-Lapse Photography) A Galvanically Isolated Thermistor Digitizer Acoustic Thermometry Measures Temperature To 0.1 Degree Clock Tunable, Filter Based Sine Wave Generator Clock Tuned, Highly Selective Notch Filter Consecutive Test Sequencer Crossover Gate—Break-Before-Make Interval Timer Delayed One Shot Energy-Tripped Circuit Breaker Trips After a Time Interval That Varies as a Function of Sensed Load Current Isolated PWM (5% to 95%) Controller Light to Frequency Converter LTC6945 Wideband Point-to-Point Radio Local Oscillator LTC6946-2 Driving a Passive Downconverting Mixer Motor Speed/Direction Control for Full H-Bridge (Locked Anti-Phase Drive) On-Time Programmable Pulsed Solenoid Driver Platinum RTD Digitizer Accurate within 1° Over 0°C to 100°C Pulse Staircase Ramp Generator Quadrature Sine Wave Oscillator. Voltage Controlled Frequency Range from 2Hz to 18kHz with 1VP-P Constant Output Amplitude Ratiometric Sensor to Pulse Width, Non-Inverting Response Relative Humidity Sensor Digitizer-Charge Pump Based Relative Humidity Sensor Digitizer-Hetrodyne Based Relative Humidity Sensor Digitizer-Time Domain Bridge Based Simple Diode Temperature Sensor With Frequency Output Simplified DC Motor Torque Control Temperature to Frequency Converter Voltage Controlled Oscillator with 16:1 Frequency Range
Relative Humidity Sensor Digitizer-Hetrodyne Based
Hetrodyne Based Humidity Transducer Digitizer Has Grounded Sensor, 2% Accuracy. Capacitively Sensed Hygrometer Beats Humidity Dependent Oscillator (C1) Against Stable Oscillator O1. Difference Frequency Is Demodulated by Q1, Converted to Pulse Form at C2. Counters Scale Output for 0kHz to 1kHz = 0% to 100% Relative Humidity
