Analog Devices Inc. AD9215BRUZ-80

Overview

AD9215BRUZ-80 from Analog Devices is a monolithic, single-supply 10-bit analog-to-digital converter (ADC) operating at 80 MSPS with 3 V supply (2.7–3.3 V), 58 dBc SNR at Nyquist, and 77 dBc SFDR. It features a differential sample-and-hold amplifier with 300 MHz input bandwidth, on-chip reference, and clock duty cycle stabilizer - deployed in ultrasound front-ends and IF sampling receivers.

For engineers reviewing the AD9215BRUZ-80 datasheet, AD9215BRUZ-80 pinout, AD9215BRUZ-80 application, or AD9215BRUZ-80 equivalent, key selection criteria include sampling rate stability at 80 MSPS, differential input flexibility (1–2 V_p-p range), low-power operation (104 mW core), and industrial temperature support (−40°C to +85°C).

Technical Context

The AD9215BRUZ-80 implements a multistage differential pipelined ADC architecture with output error correction logic, guaranteeing no missing codes across its full operating range. Its patented differential SHA supports both ac- and dc-coupled inputs up to 200 MHz and enables single-ended configurations via external biasing.

It uses a single-ended CMOS clock input with an integrated duty cycle stabilizer that maintains performance over wide pulse-width variations. Digital outputs are available in offset binary or twos complement format, with an out-of-range (OR) flag indicating signal overflow beyond the selected input span.

FAQ

What is the maximum analog input frequency supported by the AD9215BRUZ-80?

The AD9215BRUZ-80 features a 300 MHz analog input bandwidth, enabling faithful digitization of signals up to 200 MHz in practice. Its differential sample-and-hold amplifier maintains specified SNR and SFDR performance through 100 MHz input frequencies at 80 MSPS sampling, as confirmed in Figure 19 of the Rev. B datasheet.

Does the AD9215BRUZ-80 require an external reference voltage?

No, the AD9215BRUZ-80 integrates a precision voltage reference with selectable 0.5 V or 1.0 V output via the SENSE pin. External reference is optional - if used, it must be applied to the VREF pin and meet ±1 mV accuracy and 0.2 mV load regulation specs per Table 1.

How does the clock duty cycle stabilizer in the AD9215BRUZ-80 improve system design?

The AD9215BRUZ-80's clock duty cycle stabilizer allows robust operation with input clocks having 30%–70% duty cycle, eliminating the need for external clock conditioners or PLL-based cleanup circuits. This reduces bill-of-materials cost and PCB area while maintaining 58 dBc SNR and 77 dBc SFDR performance, as verified in Figure 25.

What is the pipeline latency of the AD9215BRUZ-80, and how does it affect timing alignment?

The AD9215BRUZ-80 has a fixed pipeline latency of 5 clock cycles, meaning the digital output for sample N appears at D0–D9 on the N+5th clock edge. This deterministic delay enables precise synchronization with FPGA-based decimation filters or DSP engines without variable jitter compensation logic.

Can the AD9215BRUZ-80 operate with a 2.5 V digital supply while using 3 V analog rails?

Yes - the AD9215BRUZ-80 separates analog (AVDD) and digital driver (DRVDD) supplies. AVDD operates from 2.7 V to 3.3 V, while DRVDD accepts 2.25 V to 3.6 V, allowing direct interfacing to 2.5 V FPGA I/O banks without level shifters. This is explicitly supported in Table 3 and Figure 7 of the datasheet.
