**AD7264BCPZ: A Comprehensive Technical Overview of the 14-Bit, 6-Channel SAR ADC**

The **AD7264BCPZ** from Analog Devices represents a high-performance, fully integrated solution for precision data acquisition systems requiring simultaneous sampling across multiple channels. This 14-bit, 6-channel successive approximation register (SAR) analog-to-digital converter (ADC) is engineered to deliver exceptional accuracy, speed, and versatility in a compact package, making it suitable for a wide array of industrial, medical, and communications applications.

At the core of the AD7264BCPZ are **six simultaneously sampled ADCs**. This architecture is a critical differentiator, as it ensures the precise temporal alignment of all six input channel conversions. This feature is indispensable in applications like polyphase motor control, power line monitoring, and condition monitoring systems where understanding the phase relationship between multiple signals is paramount. Each channel is built around a classic SAR ADC, renowned for its deterministic latency and high accuracy without pipeline delays.

The device operates with a **single 2.7 V to 5.25 V supply**, offering significant flexibility for both 3 V and 5 V systems. It features a **high throughput rate of up to 1 MSPS per channel**, enabling the rapid digitization of dynamic signals. The AD7264BCPZ incorporates internal reference and buffer circuits, which can be bypassed if an external reference is preferred, providing system designers with options to optimize for specific accuracy or power requirements.

A key advantage of this ADC is its **on-chip, low-noise, high-bandwidth sample-and-hold amplifier** for each channel. This ensures that even high-frequency input signals are accurately acquired without significant degradation, supporting the ADC's full bandwidth. The digital interface is serial (SPI/QSPI™/MICROWIRE™/DSP-compatible), simplifying isolation and reducing the number of pins required for communication with a host microcontroller or DSP.

The AD7264BCPZ is offered in a **32-lead LFCSP (Lead Frame Chip Scale Package)**, which is ideal for space-constrained applications. Its operating temperature range of -40°C to +105°C ensures reliable performance in harsh industrial environments. Furthermore, the device includes a **programmable sequencer**, allowing users to configure the order of channel conversion, thereby streamlining software control and improving overall system efficiency.

**ICGOO**DFIND: The AD7264BCPZ stands out as a robust and highly integrated simultaneous-sampling ADC solution. Its combination of **six precise channels, high 14-bit resolution, and 1 MSPS throughput** makes it an exceptional choice for complex multichannel systems where maintaining signal integrity and phase coherence is critical.
