The AD8310 is a complete dc to 440 MHz demodulating logarithmic amplifier with a very fast voltage-mode output, capable of driving up to 25 mA into a grounded load in under 15 ns.
The SN74LS74AN is a dual D flip-flop manufactured by Texas Instruments containing two independent positive-edge triggered D flip-flops with set and reset inputs.
The AD654 is a monolithic Voltage Frequency converter consisting of an input amplifier, a precision oscillator system, and a high current output stage.
The AD736 is a low-power, precision, monolithic True RMS-to-DC converter IC. It is laser trimmed to provide a maximum error of ±0.3 mV ± 0.3% of reading with sine wave inputs.
