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 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.
The low-power TLV9041 includes a single ultra-low-voltage (1.2 V to 5.5 V) operational amplifier (op-amps) with rail-to-rail input and output swing capabilities.
