Product details
Overview
AD9215BRUZ-105 from Analog Devices is a monolithic, single-supply 10-bit analog-to-digital converter (ADC) with 105 MSPS sampling rate, 300 MHz analog input bandwidth, and on-chip sample-and-hold amplifier and voltage reference. It operates from a 3 V supply (2.7–3.3 V), delivers 57.5 dB SNR and 75 dBc SFDR at Nyquist, and targets high-speed IF sampling in communications receivers and ultrasound front-ends.
For engineers reviewing the AD9215BRUZ-105 datasheet, AD9215BRUZ-105 pinout, AD9215BRUZ-105 application, or AD9215BRUZ-105 equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternative options, and supply support for production-grade embedded signal acquisition systems.
Technical Context
The AD9215BRUZ-105 implements a multistage differential pipelined ADC architecture with output error correction logic to guarantee 10-bit accuracy and no missing codes across −40°C to +85°C. Its patented differential SHA supports both ac- and dc-coupled inputs up to 200 MHz and configurable single-ended operation.
A dedicated clock duty cycle stabilizer maintains performance over wide input duty cycle variation, while separate AVDD (analog) and DRVDD (digital driver) supplies enable compatibility with 2.5 V or 3.3 V logic families. The OR (out-of-range) output flag signals overflow conditions independently of MSB polarity.
Key Specifications

| Max Sampling Rate | 105 MSPS - enables digitization of IF signals up to 52.5 MHz (Nyquist) without aliasing in wideband receivers. |
| SNR @ Nyquist | 57.5 dB - supports ≥9.3 ENOB for clean baseband reconstruction of high-frequency analog waveforms. |
| Spurious-Free Dynamic Range | 75 dBc - ensures strong interferer rejection in dense spectral environments like cellular basestations or medical Doppler imaging. |
| Analog Input Bandwidth | 300 MHz - allows direct sampling of broadband RF/IF signals without external pre-filtering or downconversion. |
| Power Consumption | 120 mW core + 25 mW digital driver - enables low-power portable instrumentation and battery-powered scopemeters. |
| Differential Nonlinearity | ±0.6 LSB max - preserves monotonicity and linearity critical for closed-loop control and precision measurement applications. |
Pinout & Package
AD9215BRUZ-105 is packaged in a 28-lead TSSOP (RU-28) with exposed pad thermal enhancement. Pin 1 is OR (Out-of-Range indicator); pins 9 and 10 are VIN+ and VIN− for fully differential analog input; pins 13 and 14 accept CLK and PDWN; pins 17–22 and 25–28 deliver D0 (LSB) through D9 (MSB) data outputs; AVDD/AGND and DRVDD/DRGND are segregated for noise isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OR (Pin 1) | Overflow detection output | Asserts high when input exceeds ±VREF range-used with MSB to distinguish high/low saturation in real-time signal monitoring. |
| MODE (Pin 2) | Data format & DCS control | Selects offset binary/twos complement output and enables/disables clock duty cycle stabilizer via AVDD/3 threshold. |
| VIN+ / VIN− (Pins 9, 10) | Differential analog input | Accepts 1 Vp-p to 2 Vp-p input span; supports single-ended use via internal bias; 2 pF input capacitance minimizes track-and-hold loading. |
| CLK (Pin 13) | Sampling clock input | Rising-edge triggered; accepts 5–105 MSPS clocks; internal duty cycle stabilizer tolerates 30%–70% duty cycle without SNR degradation. |
| D0–D9 (Pins 17–22, 25–28) | Parallel digital output bus | CMOS-compatible outputs referenced to DRVDD (2.25–3.6 V); 5 pF load capability ensures robust timing margin in FPGA/ASIC interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Single 3 V supply operation | Eliminates dual-rail power design complexity; AVDD (2.7–3.3 V) and DRVDD (2.25–3.6 V) decoupling enables mixed-voltage system integration. |
| On-chip reference & SHA | Reduces BOM count by removing external REF and op-amp circuitry; 1 V or 0.5 V reference modes simplify gain scaling for varying sensor outputs. |
| Flexible analog input range | 1 Vp-p to 2 Vp-p programmable span accommodates diverse signal sources-from low-noise ultrasound transducers to high-level IF mixers-without external attenuation. |
| Low power at 105 MSPS | 120 mW analog core + 25 mW digital driver enables thermally constrained designs such as handheld diagnostic equipment and compact test instruments. |
| Pipeline latency of 5 cycles | Predictable, fixed delay simplifies timing closure in synchronous digital systems and enables deterministic FIR filtering or real-time envelope detection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9226ARZ | 12-bit, 65 MSPS; higher resolution but lower speed; 50 mW lower power at 65 MSPS. | Better suited for DC-coupled precision measurement where SNR > 70 dB is required over bandwidth < 30 MHz. | Choose AD9226ARZ when resolution outweighs speed-e.g., spectroscopy or vibration analysis-not for IF sampling above 40 MHz. |
| ADS5271IPFP | 10-bit, 65 MSPS octal ADC; lower per-channel power (35 mW), no on-chip reference, requires external clock buffer. | Targeted at multi-channel time-interleaved systems (e.g., MRI coil arrays) rather than single high-fidelity IF path. | Choose ADS5271IPFP only for space-constrained, multi-channel acquisition where board-level clock distribution and reference sharing are feasible. |
Compared with AD9215BRUZ-105, AD9226ARZ trades 40 MSPS speed for +2 bits resolution and lower noise floor, while ADS5271IPFP sacrifices single-channel performance and integration for parallel channel density-neither offers pin compatibility or identical timing behavior.

FAQ
What is the maximum analog input frequency supported by the AD9215BRUZ-105?
The AD9215BRUZ-105 features a 300 MHz analog input bandwidth, enabling faithful digitization of signals up to 300 MHz under small-signal conditions. For Nyquist-limited sampling at 105 MSPS, the practical full-power input frequency is 52.5 MHz; however, the device maintains usable SFDR beyond 100 MHz-as verified in Figure 18 of the Rev. B datasheet with 75 dBc at 100.3 MHz.
Does the AD9215BRUZ-105 require an external voltage reference?
No, the AD9215BRUZ-105 integrates a precision voltage reference with ±2 mV output error in 1 V mode and ±1 mV in 0.5 V mode. External reference is optional via VREF pin; default operation uses internal reference selected by SENSE pin state. This eliminates external reference ICs and associated layout sensitivity in most applications.
How does the clock duty cycle stabilizer function in the AD9215BRUZ-105?
The AD9215BRUZ-105's clock duty cycle stabilizer (DCS) actively corrects input clock asymmetry, maintaining SNR and SFDR performance across 30%–70% duty cycle-verified in Figure 25 of the datasheet. When enabled (MODE = AVDD/3), DCS reduces sensitivity to oscillator or PLL output distortion, eliminating need for external clock conditioning circuits.
What is the pipeline latency of the AD9215BRUZ-105 and how does it affect system timing?
The AD9215BRUZ-105 has a fixed pipeline latency of 5 clock cycles-measured from CLK rising edge to valid D0–D9 output. This deterministic delay simplifies synchronization with FPGAs or DSPs, enables precise trigger alignment in oscilloscopes, and allows predictable insertion of digital filters without variable buffering.
Can the AD9215BRUZ-105 operate with a 2.5 V digital supply while using 3 V analog supply?
Yes-the AD9215BRUZ-105 separates AVDD (2.7–3.3 V, analog core) and DRVDD (2.25–3.6 V, digital output drivers). Using 3 V AVDD and 2.5 V DRVDD is explicitly supported per Table 3 and enables direct interface to 2.5 V FPGA I/O banks without level shifters, reducing signal integrity risk and board complexity.
