Product Details

The AD8253 is an instrumentation amplifier with digitally programmable gains that has gigaohm (GΩ) input impedance, low output noise, and low distortion, making it suitable for interfacing with sensors and driving high sample rate analog-to-digital converters (ADCs).

It has a high bandwidth of 10 MHz, low THD of −110 dB, and fast settling time of 780 ns (maximum) to 0.001%. Offset drift and gain drift are guaranteed to 1.2 µV/°C and 10 ppm/°C, respectively, for G = 1000. In addition to its wide input common voltage range, it boasts a high common-mode rejection of 100 dB at G = 1000 from dc to 20 kHz. The combination of precision dc performance coupled with high speed capabilities makes the AD8253 an excellent candidate for data acquisition. Furthermore, this monolithic solution simplifies design and manufacturing and boosts performance of instrumentation by maintaining a tight match of internal resistors and amplifiers.

The AD8253 user interface consists of a parallel port that allows users to set the gain in one of two different ways (see Figure 1 for the functional block diagram). A 2-bit word sent via a bus can be latched using the WR input. An alternative is to use transparent gain mode, where the state of logic levels at the gain port determines the gain.

The AD8253 is available in a 10-lead MSOP package and is specified over the −40°C to +85°C temperature range, making it an excellent solution for applications where size and packing density are important considerations.

The AD8253 is used to measure the voltage drop over a shunt resistor in a lab programmable current source. The adjustable gain 1/10/100/1000 ensures good input signals to an ADC over a very wide range, while keeping the shunt low. Very handy device.

In my opinion AD8253 is fantastic product.
I test this IC in several different devices and results are very good. AD8253 is for me better as other similar instrumental amplifiers in his class produced by AD competitors. Unfortunately I see not strong technical analyse tools support on AD website for AD8253 and other AD products. There are AD8253 simulation model but it is very archaic text edited form of .cir file, instead in Cadence Orcad or Micro-Cap library files which are very popular today. Because I found troubles on the way of importing AD8253.cir file to new simulation software (syntax and other errors) and I'm still not sure that final results are correct - I ask about Micro-Cap/OrCad libraries your ADI support center and I wait for answer.

almost ideal, but...
It would be highly desirable if ad8253 had internal buffer for REF input. I believe that this would be not very difficult/expensive to implement for the manufacturer, but such a feature would make it much more easy to apply ad8253 in the circuits which use internal ADC of the microcontroller, necessarily having single supply, but intended to be able to measure bipolar input signals. Of course, as a user, I would like to see as low noise level as possible, but I believe that AD has already done all its best to decrease it as much as physical limitations allow. Probably, it would be worth considering developing similar part with input multiplexer (and/or two amplifiers in one package). Anyway, I estimate the capabilities of ad8253 as very good.
