AD8224HACPZ-R7

Analog Devices Inc.
The AD8224 is the first single-supply, JFET input instrumentation amplifier available in the space-saving 16-lead, 4 mm × 4 mm LFCSP. It requires the same board area as a typical single instrumentation amplifier yet doubles the channel density and offers a lower cost per channel without compromising performance.Designed to meet the needs of high performance, portable instrumentation, the AD8224 has a minimum common-mode rejection ratio (CMRR) of 86 dB at dc and a minimum CMRR of 80 dB at 10 kHz for G = 1. Maximum input bias current is 10 pA and typically remains below 300 pA over the entire industrial temperature range. Despite the JFET inputs, the AD8224 typically has a noise corner of only 10 Hz.With the proliferation of mixed-signal processing, the number of power supplies required in each system has grown.Designed to alleviate this problem, the AD8224 can operate on a ±18 V dual supply, as well as on a single +5 V supply. The device’s rail-to-rail output stage maximizes dynamic range on the low voltage supplies common in portable applications. Its ability to run on a single 5 V supply eliminates the need for higher voltage, dual supplies. The AD8224 draws 750 μA of quiescent current per amplifier, making it ideal for battery powered devices.In addition, the AD8224 can be configured as a single-channel, differential output, instrumentation amplifier. Differential outputs provide high noise immunity, which can be useful when the output signal must travel through a noisy environment, such as with remote sensors. The configuration can also be used to drive differential input ADCs.For a single-channel version, use the AD8220.Applications Medical instrumentation Precision data acquisition Transducer interfaces Differential drives for high resolution input ADCs Remote sensors

Analog Devices Inc.
The AD8231 is a low drift, rail-to-rail, instrumentation amplifier with software-programmable gains of 1, 2, 4, 8, 16, 32, 64, or 128. The gains are programmed via digital logic or pin strapping.The AD8231 is ideal for applications that require precision performance over a wide temperature range, such as industrial temperature sensing and data logging. Because the gain setting resistors are internal, maximum gain drift is only 10 ppm/°C for gains of 1 to 32. Because of the auto-zero input stage, maximum input offset is 15 μV and maximum input offset drift is just 50 nV/°C. CMRR is 80 dB for G = 1, increasing to 110 dB at higher gains.The AD8231 also includes an uncommitted op amp that can be used for additional gain, differential signal driving, or filtering. Like the in-amp, the op amp has an auto-zero architecture, rail-to-rail input, and rail-to-rail output.The AD8231 includes a shutdown feature that reduces current to a maximum of 1 μA. In shutdown, both amplifiers also have a high output impedance, which allows easy multiplexing of multiple amplifiers without additional switches.The AD8231 is specified over the extended industrial tempera-ture range of −40°C to +125°C. It is available in a 4 mm × 4 mm 16-lead LFCSP.Applications Pressure and strain transducers Thermocouples and RTDs Programmable instrumentation Industrial controls Weigh scales Automotive controls

AD8236ARMZ-R7

Analog Devices Inc.
The AD8236 is the lowest power instrumentation amplifier in the industry. It has rail-to-rail outputs and can operate on voltages as low as 1.8 V. Its 40 μA maximum supply current makes it an excellent choice in battery-powered applications.The AD8236’s high input impedance, low input bias current of 1 pA, high CMRR of 110 dB (G = 100), small size, and low power offer tremendous value. It has a wider common-mode voltage range than typical three-op-amp instrumentation amplifiers, making this a great solution for applications that operate on a single 1.8 V or 3 V supply. An innovative input stage allows for a wide rail-to-rail input voltage range without the crossover distortion common in other designs.The AD8236 is available in an 8-lead MSOP and is specified over the industrial temperature range of −40°C to +125°CApplicationsMedical instrumentationLow-side current sensePortable devices

AD8666WARZ-RL

Analog Devices Inc.
The AD866x family are single supply, rail-to-rail output amplifiers with low noise performance featuring an extended operating range with supply voltages up to 16 V. They also feature low input bias currents, wide signal bandwidth, and low input voltage and current noise. For lower offset voltage, choose the AD8661/AD8662/AD8664 family.The combination of low offsets, very low input bias currents, and wide supply range make these amplifiers useful in a wide variety of cost sensitive applications normally associated with much higher priced JFET amplifiers. Systems using high impedance sensors, such as photo diodes, benefit from the combination of low input bias current, low noise, and low offset and bandwidth. The wide operating voltage range matches high performance ADCs and DACs. Audio applications and medical monitoring equipment can take advantage of the high input impedance, low voltage and current noise, wide bandwidth, and the lack of popcorn noise found in many other low input bias current amplifiers.The AD866x family is specified over the extended industrial temperature range (−40° to +125°C).

Analog Devices Inc.
The ADA4927 is a low noise, ultralow distortion, high speed, current feedback differential amplifier that is an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz. The output common-mode level can easily be matched to the required ADC input common-mode levels. The internal common-mode feedback loop provides exceptional output balance and suppression of even-order distortion products.Differential gain configurations are easily realized using an external feedback network comprising four resistors. The current feedback architecture provides loop gain that is nearly independent of closed-loop gain, achieving wide bandwidth, low distortion, and low noise at higher gains and lower power consumption than comparable voltage feedback amplifiers.The ADA4927 is fabricated using the Analog Devices, Inc., silicon-germanium complementary bipolar process, enabling very low levels of distortion with an input voltage noise of only 1.3 nV/√Hz. The low dc offset and excellent dynamic performance of the ADA4927 make it well suited for a wide variety of data acquisition and signal processing applications.The ADA4927-1 is available in a Pb-free, 3 mm × 3 mm 16-lead LFCSP, and the ADA4927-2 is available in a Pb-free, 4 mm × 4 mm 24-lead LFCSP.
