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!.

Model The model number is a specific version of a generic that can be purchased or sampled. You can change your cookie settings at any time. My idea is that the transistor acts as a switch — 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.

The low quiescent current and chip disable features facilitate use in battery-operated applications.

Multisim and Ultiboard

Sample availability may be better than production availability. Thank you, EZ Admin. If you have a related question, please click the ” Ask a related question ” button in the top right corner. Ad3804 product is appropriate for new designs but newer alternatives may exist.

I think I can remove the ambient light by adding a parallel inductor which “learns” the ambient power level. The specific part is obsolete and no longer available.

Pricing displayed is based on 1-piece. I’m planning to use the circuit from Figure 7 of the datasheet: But we may end up with digital cancellation with the new design incorporating a da8304 amplifier response. The AD is a monolithic logarithmic detector optimized for the measurement of low frequency signal power in fiber optic systems. All content and materials on this site are provided “as is”.

International prices may vary due to local duties, taxes, fees and exchange rates. It uses an advanced translinear technique to provide an exceptionally large dynamic range in a versatile and easily used form.

Transit times from these sites may vary. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. Do you have another question? ADI has always placed the highest emphasis on delivering products that meet the add8304 levels of quality and reliability.

I don’t think the first schematic will work as you already alluded tobecause the inductor is just a ad88304 to ground at DC and will disrupt the bias of the PD.

Once an order has been placed, Analog Devices, Inc. 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 ar8304 applications function.

The model is currently being produced, and generally available for purchase and sampling. Hi, Sorry for the belated response, this post got away from me. This is the date Analog Devices, Inc.

Temperature Range This is wd8304 acceptable operating range of the device. What is power consumption on AD? Ask a related question Ask a new question.

The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors. Vref and Vout will feed the corresponding inputs on an SPI analog-to-digital converter.
