Analog Devices Inc. AD9215BRU-105

Overview

AD9215BRU-105 from Analog Devices is a 10-bit, 105 MSPS monolithic analog-to-digital converter (ADC) with single 3 V supply operation (2.7 V to 3.3 V), differential input bandwidth of 300 MHz, and on-chip sample-and-hold amplifier and voltage reference. It delivers SNR = 57.5 dB and SFDR = 77 dBc at Nyquist, supporting IF sampling in communications receivers and ultrasound equipment.

For engineers reviewing the AD9215BRU-105 datasheet, AD9215BRU-105 pinout, AD9215BRU-105 application, or AD9215BRU-105 equivalent, key selection considerations include its 105 MSPS maximum conversion rate, 120 mW core power consumption at full speed, DNL = ±0.25 LSB, flexible 1 V p-p to 2 V p-p analog input range, and clock duty cycle stabilizer for robust timing tolerance.

Technical Context

The AD9215BRU-105 employs a multistage differential pipelined ADC architecture with output error correction logic, enabling guaranteed 10-bit accuracy and no missing codes across −40°C to +85°C. Its patented differential sample-and-hold amplifier supports both single-ended and differential configurations with 300 MHz analog input bandwidth.

It features a dedicated digital output driver supply (DRVDD = 2.25 V to 3.6 V) independent from the analog supply (AVDD = 2.7 V to 3.3 V), allowing interface compatibility with 2.5 V and 3.3 V logic families. The out-of-range (OR) signal provides overflow detection synchronized to the pipeline latency of 5 clock cycles.

FAQ

What is the maximum analog input frequency supported by the AD9215BRU-105?

The AD9215BRU-105 features a 300 MHz analog input bandwidth, enabling accurate digitization of signals up to 100 MHz at 105 MSPS sampling rate while maintaining specified SNR and SFDR. This bandwidth supports direct IF sampling without aliasing for many wireless and medical applications.

Does the AD9215BRU-105 require an external voltage reference?

No, the AD9215BRU-105 includes an on-chip voltage reference configurable for 0.5 V or 1.0 V output via the SENSE pin. This eliminates the need for external reference ICs and simplifies design for portable and space-constrained systems where the AD9215BRU-105 serves as a self-contained ADC solution.

How does the clock duty cycle stabilizer in the AD9215BRU-105 improve system robustness?

The AD9215BRU-105's integrated clock duty cycle stabilizer (DCS) corrects wide variations in input clock duty cycle (40%–60%), preserving SNR and SFDR performance without requiring precision clock generation. This allows use of simpler, lower-cost clock sources in systems where the AD9215BRU-105 is deployed.

What is the pipeline latency of the AD9215BRU-105 and how does it affect system timing?

The AD9215BRU-105 has a fixed pipeline latency of 5 clock cycles, meaning the digital output for a given sample appears 5 clocks after the sampling edge. This deterministic delay simplifies synchronization in FPGA-based digital downconverters and real-time control loops where the AD9215BRU-105 is the primary acquisition element.

Can the AD9215BRU-105 operate from a 2.5 V supply?

No-the AD9215BRU-105 requires AVDD between 2.7 V and 3.3 V for analog core operation; 2.5 V is below the minimum specification. However, its digital output drivers accept DRVDD from 2.25 V to 3.6 V, enabling interface with 2.5 V logic families while the AD9215BRU-105 core runs at 3.0 V.
