Integrated Single-Supply, Rail-to-Rail Instrumentation Amplifier Packs Performance
The AD8223 is a low cost, integrated single-supply instrumentation amplifier (in-amp) that delivers rail-to-rail output swing on a single supply (3 V to 25 V). The device offers superior user flexibility by allowing single-gain set resistor programming. With no external resistor, the AD8223 is configured for G = 5; with an external resistor, the AD8223 can be programmed for gains up to 1000. The AD8223 has a wide input common-mode range and can amplify signals with a commonmode voltage 150 mV below ground. It is available in 8-lead MSOP and SOIC packages with an operating temperature range of –40°C to +85°C.
AD8223 Features Dual Difference Amplifier Offers Higher System Performance and Channel Density at an Attractive Price The AD8270 is a dual-channel, pin-programmable difference amplifier with internal gain setting resistors that offer unmatched dc precision with ac bandwidth specifications. The device combines 10 MHz of bandwidth and a 30 V/µs slew rate, making it ideally suited for advanced applications such as high speed industrial control measurement and multichannel systems where high bandwidth and SNR are required. With no external components, the AD8270 can be configured as a high performance difference amplifier (G = 0.5, 1, or 2), inverting amplifier (G = 0.5, 1, or 2), or noninverting amplifier (G = 1.5, 2, or 3). It is offered in a 4 mm × 4 mm, 16-lead LFCSP, supporting double the channel density at a lower cost per channel vs. competitive solutions with no compromise in performance. A standard pinout 14-lead SOIC (G = 0.5 or 2) version of this device, the AD8273, is also available. Both the AD8270 and AD8273 operate on single and dual supplies and only require 2.5 mA maximum supply current per amplifier. Each device is fully ROHS compliant and is specified over the industrial temperature range of –40°C to +85°C. The AD8270's dc accuracy, when combined with a high slew rate, makes it an optimal ADC driver for ADI's broad portfolio of PulSAR® ADCs that includes the AD7980 and AD7688. The ADR43x and ADR36x low noise voltage references, with sync and source capabilities, are recommended compatible products for the AD8270 and AD8273 difference amplifiers.
