Description of Product AD7788ARMZ-REEL from Analog Devices Inc.

The AD7788ARMZ-REEL is a high-precision, low-power, 16-bit sigma-delta (ΣΔ) Analog-to-Digital Converter (ADC) offered by Analog Devices Inc., a leader in high-performance semiconductors for signal processing applications. This ADC is specifically designed for applications requiring high accuracy measurement under low power conditions, making it an ideal choice for portable or battery-powered instruments.

The device operates from a single 2.7 V to 5.25 V power supply and features a very low power consumption rate, drawing only 75 μA typical when in normal operation mode. It also includes a power-down mode that reduces the current consumption to 1 μA typical, which is particularly useful for extending battery life in portable systems.

The AD7788ARMZ-REEL incorporates a ΣΔ modulator and programmable gain amplifier (PGA), allowing it to convert analog input signals directly without the need for signal conditioning. The input signal range can be optimized using the programmable gain settings, which can be set to 1, 2, 4, or 8 times amplification. This flexibility enables the ADC to handle a wide range of sensor outputs, including those from thermocouples, RTDs, and pressure sensors.

This ADC also features an on-chip oscillator, eliminating the need for external clock sources and simplifying the overall design. The device supports a SPI-compatible serial interface, enabling easy communication with microprocessors and DSPs. The AD7788ARMZ-REEL comes in a compact, 10-lead MSOP (Mini Small Outline Package) that is suitable for space-constrained applications.

With its exceptional performance and low power consumption, the AD7788ARMZ-REEL from Analog Devices Inc. is an excellent choice for precision measurement in a variety of applications such as industrial process control, instrumentation, smart transducers, and medical equipment.
