AD7262BCPZ, or Analog Devices 7262BCPZ, is a 2-channel, low-power (25 µA) electrostatic discharge (ESD) protected integrated circuit, which provides 12-bit resolution ofanalog-to-digital conversion across the sampled input channels when used with a single +4.5 to +5.5 V supply. It is designed for use in portable and battery poweredapplications.AD7262BCPZ is part of the AD7262 family of parts, which all offer comparable features for analog-to-digital conversion in multiple configurations. The AD7262BCPZoffers, among other features, single/dual channel selection, low power consumption, and a conversion rate of 200 kHz.AD7262BCPZ Application FieldAD7262BCPZ is a very efficient component for performing analog-to-digital conversion. Any applications requiring the conversion of analog signals to digital signalsare potential candidates for AD7262BCPZ utilization. Clearly, audio and video applications can benefit from the sampling capabilities of this component. Healthcare devices,including medical electronics and patient monitoring, are prime examples of where AD7262BCPZ can be employed.Additionally, wireless communication equipment such as cellular phones, sending or receiving pagers or GPS receivers can make use ofthe component as well.Other associated devices like sensors, digital pots and touchscreens can also be digitized and AD7262BCPZ is ideal for that.AD7262BCPZ Working PrincipleAD7262BCPZ works on the differential and single-ended principles. Differential input implies that the component compares two analog inputs and the conversion resolution is based on the difference between them.Single-ended conversion implies that the component compares one analog input versus a fixed reference voltage.AD7262BCPZ has two primary analog input ports for differential inputs and a secondary single-ended input port for comparison. It also has two digital output ports for thecompleted conversion (12-bit resolution).The analog input range is typically 0V-5V and it has a sample rate of 200kHz. The input impedance is 2kohm and its output impedance is 10kohm.The component will typically perform the following sequence of operations to complete a conversion cycle:1. Select an active input port.2. Perform analog to digital conversion using delta-sigma modulator.3. Calculate the digital output data.4. Output the digital output data.AD7262BCPZ can operate in both single-ended and differential modes. In single-ended mode, the component will compare the input voltage against a reference voltage andoutput a 12-bit representation of the result.In differential mode, the component will compare the two inputs and output a 12-bit representation of the difference.AD7262BCPZ also features an on-chip noise filter and a temperature sensor, which can be used in low-power applications or in applications where the performance ofthe component must be precisely controlled.ConclusionAD7262BCPZ is an incredibly efficient integrated circuit for performing analog-to-digital conversion. It is ideal for portable and battery powered applications as it requiresonly a single +4.5 to +5.5 V supply and has a low-power consumption (25 µA).Applications for AD7262BCPZ include, but are not limited to: audio and video, healthcare equipment, wireless communication devices, sensors, digital pots and touchscreens. It features two primary analog input ports for differential inputs and a secondary single-ended input port for comparison, and its sample rate is 200kHz.The component operates by first selecting an active input port, then performing the conversion using a delta-sigma modulator and finally calculating the digitaloutput data and outputting it.AD7262BCPZ also includes an on-chip noise filter and a temperature sensor, which make it an even more versatile and efficient component.
