Analog Devices Inc. AD9215BRU-80

Overview

AD9215BRU-80 from Analog Devices is a monolithic, single-supply 10-bit analog-to-digital converter (ADC) with 80 MSPS sampling rate, 3 V operation (2.7–3.3 V), and differential input bandwidth up to 300 MHz. It integrates a sample-and-hold amplifier (SHA), on-chip voltage reference, and clock duty cycle stabilizer, and is used in IF sampling receivers and portable test equipment requiring high dynamic range at low power.

For engineers reviewing the AD9215BRU-80 datasheet, AD9215BRU-80 pinout, AD9215BRU-80 application, or AD9215BRU-80 equivalent, this page delivers verified specifications, functional context, package mapping, real-world use cases, and validated alternative options - all grounded in Rev. B datasheet and official Analog Devices documentation.

Technical Context

The AD9215BRU-80 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 SHA supports both differential and single-ended configurations with user-selectable input ranges (1 V_p-p or 2 V_p-p) and maintains SNR = 58 dBc at Nyquist.

A dedicated clock duty cycle stabilizer ensures stable performance over wide input duty cycle variations, while separate AVDD (analog) and DRVDD (digital driver) supplies allow interfacing with 2.5 V or 3.3 V logic families. The OR (out-of-range) output flag provides overflow detection synchronized to the pipeline latency of 5 clock cycles.

Key Specifications

Pinout & Package

AD9215BRU-80 is packaged in a 28-lead TSSOP (RU-28) with exposed pad not present; pin 15–16 and 25–28 are DNC (do not connect). All analog and digital grounds are separated (AGND/DRGND), and the exposed pad is absent - unlike the CP-32 variant.

FAQ

What is the maximum analog input frequency supported by AD9215BRU-80?

The AD9215BRU-80 specifies an analog input bandwidth of 300 MHz, meaning it can accurately digitize signals with frequency content up to 300 MHz before significant amplitude roll-off occurs. This enables direct sampling of IF signals in communications systems and harmonics in ultrasound applications, though practical Nyquist-limited input is ≤40 MHz at 80 MSPS sampling.

Does AD9215BRU-80 require an external voltage reference?

No. AD9215BRU-80 includes an on-chip voltage reference configurable for 0.5 V or 1.0 V output via the SENSE pin, eliminating the need for external reference components. The internal reference exhibits ±230 ppm/°C drift and ±2 mV output error in 1 V mode, supporting stable operation across −40°C to +85°C.

How does the clock duty cycle stabilizer in AD9215BRU-80 improve system robustness?

The clock duty cycle stabilizer in AD9215BRU-80 actively corrects input clock duty cycle deviations between 30% and 70%, maintaining SNR and SFDR performance without requiring precise clock synthesis. This allows use of standard PLLs or crystal oscillators with relaxed duty cycle specs, reducing layout sensitivity and improving yield in high-volume production.

What is the pipeline latency of AD9215BRU-80, and why does it matter?

AD9215BRU-80 has a fixed pipeline latency of 5 clock cycles from sample initiation (CLK rising edge) to valid output data. This deterministic delay is essential for time-critical applications like digital downconversion or real-time trigger alignment, enabling precise synchronization with FPGA logic or DSP firmware without variable jitter compensation.

Can AD9215BRU-80 operate with a 2.5 V digital supply while using 3 V analog supply?

Yes. AD9215BRU-80 supports independent supply rails: AVDD = 2.7–3.3 V for analog circuitry and DRVDD = 2.25–3.6 V for digital outputs. Using DRVDD = 2.5 V allows direct interfacing with 2.5 V FPGA I/O banks, while maintaining full analog performance - confirmed in Table 3 of the Rev. B datasheet.
