Description

ADI’s AD623 is single- or dual-supply instrumentation amplifier for rail-to-rail output with a voltage range of 3 V to 12 V. With no need for an external resistor, this amplifier is perfect for low power consumption, low board space, and lower cost count. The high accuracy with 800 kHz bandwidth and high gain of 1 to 1000 is perfect for battery applications. The devices come in 8-pin packages of PDIP, SOIC, and MSOP and has a -40°C to +85°C temperature range. The AD623 instrumentation amplifier is ideal for battery and wearable applications such as medical, fitness, and gaming applications.

APPLICATIONS

Low power medical instrumentation Transducer interfaces Thermocouple amplifiers Industrial process controls Difference amplifiers Low power data acquisition

The is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing 12 V supply. The AD623 offers superior user flexibility by allowing single gain set resistor programming and by conforming to the 8-lead industry standard pinout configuration. With no external resistor, the AD623 is configured for unity gain = 1), and with an external resistor, the AD623 can be programmed for gains to 1000.

The AD623 holds errors to a minimum by providing superior ac CMRR that increases with increasing gain. Line noise, as well as line harmonics, are rejected because the CMRR remains constant to 200 Hz. The AD623 has a wide input commonmode range and can amplify signals that have a common-mode voltage 150 mV below ground. Although the design of the AD623 was optimized to operate from a single supply, the AD623 still provides superior performance when operated from a dual voltage supply to 6.0 V). Low power consumption at 3 V), wide supply voltage range, and rail-to-rail output swing make the AD623 ideal for battery-powered applications. The rail-to-rail output stage maximizes the dynamic range when operating from low supply voltages. The AD623 replaces discrete instrumentation amplifier designs and offers superior linearity, temperature stability, and reliability in a minimum of space.
