AD8304 PDF

Analog Devices Inc. AD Series Logarithmic Amplifiers are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for Analog. The ADEVALZ is an evaluation board for AD dB logarithmic amplifier with photo diode interface. The AD is a monolithic logarithmic detector. 18 Aug I am trying to replace AD with LOG Could you please help provide a comparison table between LOG and AD? Thanks!.

It uses an advanced translinear technique to provide an exceptionally large dynamic range in a versatile and easily used form. Model The model number is a specific version of a generic that can be purchased or sampled. The model has not been released to general production, but samples may be available. The product is appropriate for new designs but newer ad8340 may exist.

The light source will be pulsed sequenced through several wavelengths, actuallyand xd8304 ADC measurements will be synchronized with the source pulses. When using low supply voltages, the log slope is readily altered to fit the available span. The package for this IC i. Hi David, Although the AD and LOG provide similar log amplifier functions, they are different enough in their internal circuits, gain, reference voltage, package options, etc, that is better for us to assess whether the LOG is usable for the intended applications function.

Here’s an adaptation of a current-mode as8304 circuit: At least one model within this product family is in production and available for purchase.

Sample availability may be better than production availability. Use of the information on this site may require a license from a third party, or a license from TI.

Here’s an adaptation of a current-mode sample-and-hold circuit:. Aug 18, 2: Pin Count Pin Count is the number of pins, balls, or pads on the device. Please Select a Language. The model is currently being produced, and generally available for purchase and sampling. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors.

My idea is that the transistor acts as a xd8304 — while the source is turned off, the transistor disconnects the TIA and the RLC circuit charges until the current is all passing through the inductor.
