Overview
The AD7760BSVZ is a high-performance, 24-bit Sigma-Delta (Σ-Δ) analog-to-digital converter (ADC) produced by Analog Devices Inc. This device combines wide input bandwidth and high speed, making it ideal for high-speed data acquisition applications. The AD7760 features an integrated buffer, a differential amplifier for signal buffering and level shifting, and a low-pass digital Finite Impulse Response (FIR) filter. These integrated components simplify the design process by reducing the need for external signal conditioning and antialiasing filters.
