Product details
Overview
AD9051BRS-2V from Analog Devices is a 10-bit, 60 MSPS monolithic analog-to-digital converter with integrated track-and-hold and voltage reference, designed for high-performance digitization in medical imaging, digital communications, and instrumentation systems. It operates from a single 5 V supply, delivers 9.3 ENOB at 10.3 MHz input, consumes 250 mW at full rate, and supports selectable 50 MHz/130 MHz input bandwidth.
For engineers reviewing the AD9051BRS-2V datasheet, AD9051BRS-2V pinout, AD9051BRS-2V application, or AD9051BRS-2V equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for signal acquisition system design.
Technical Context
The AD9051BRS-2V uses a two-step subranging architecture with digital error correction to guarantee true 10-bit accuracy. Its differential analog input is internally biased at 2.5 V and features overrange detection with clamping, locking outputs to all-0 or all-1 states when input exceeds 1.875 V–3.125 V range.
Digital outputs are CMOS with isolated VDD pins (20, 22), enabling direct 3 V or 5 V logic compatibility. The device exhibits five-pipeline-stage latency, with data valid one propagation delay after the rising edge of the TTL-compatible ENCODE signal (Pin 13).
Key Specifications

| Sampling Rate | 60 MSPS maximum - supports real-time digitization of IF signals up to 30 MHz Nyquist zone |
| Effective Number of Bits | 9.3 ENOB at fIN = 10.3 MHz - ensures ≥58 dB SNR for precision baseband capture |
| Input Bandwidth | Selectable 50 MHz (BWSEL = VD) or 130 MHz (BWSEL = NC) - enables trade-off between noise floor and wideband response |
| Power Consumption | 250 mW at 60 MSPS - optimized for low-power embedded acquisition without external cooling |
| Analog Input Range | 1.25 VPP centered at 2.5 V (1.875 V to 3.125 V) - compatible with standard op-amp driver stages like AD820 |
| Reference | On-chip 2.5 V bandgap reference (Pin 3) with ±5% adjustability via external VREFIN (Pin 4) - allows gain scaling across multi-channel systems |
Pinout & Package
AD9051BRS-2V is housed in a 28-lead Shrink Small Outline Package (SSOP), JEDEC MO-150-AH compliant, with 0.65 mm pitch and 10.2 mm × 7.6 mm body size. Thermal pad is not present; coplanarity ≤ 0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 7, 12, 21, 23 | GND | Signal and power ground return paths - must be connected to low-impedance analog ground plane |
| 2, 8, 11 | VD | Analog 5 V supply - powers T/H, ADC core, and reference circuits; requires local 0.1 µF + 10 µF decoupling |
| 3 | VREFOUT | 2.5 V internal reference output - used as default ADC reference when shorted to Pin 4 |
| 4 | VREFIN | Reference amplifier input - accepts external 2.5 V reference for improved tempco or gain tuning |
| 5 | BWSEL | Bandwidth select control - logic high (VD) sets 50 MHz input BW; open or grounded sets 130 MHz |
| 9, 10 | AINB / AIN | Differential analog input pair - internally biased at 2.5 V; supports single-ended drive with matched termination |
| 13 | ENCODE | TTL-compatible clock input - rising edge initiates conversion and latches output data after 5 pipeline stages |
| 14 | OR | Out-of-range flag - active-high signal indicating input violation of 1.875–3.125 V window |
| 15, 16–19, 24–27, 28 | D9–D0 | 10-bit parallel CMOS outputs - MSB (D9) on Pin 15, LSB (D0) on Pin 28; level set by VDD (Pins 20, 22) |
| 20, 22 | VDD | Digital output supply - independently configurable for 3 V or 5 V logic interfacing |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9203ARUZ | 10-bit, 40 MSPS; lower power (100 mW); no on-chip T/H or reference; requires external clock buffer | Better suited for space-constrained portable instruments where encode rate < 40 MSPS suffices | Choose AD9203ARUZ when system clock jitter budget is tight and external T/H is already present |
| ADS5271IPFP | 10-bit, 65 MSPS; LVDS outputs; separate analog/digital supplies; no integrated reference | Optimized for multi-channel synchronized capture in telecom baseband cards with FPGA LVDS interfaces | Choose ADS5271IPFP when board-level routing supports differential signaling and external reference is preferred for channel matching |
Compared with AD9051BRS-2V, AD9203ARUZ trades sampling speed and integration for lower power and smaller footprint, while ADS5271IPFP offers higher speed and LVDS noise immunity at the cost of increased layout complexity and external component count.

FAQ
What is the exact input voltage range specification for AD9051BRS-2V?
The AD9051BRS-2V has a nominal analog input range of 1.875 V to 3.125 V (1.25 VPP centered at 2.5 V). This range is defined by the internal 2.5 V reference and remains linearly scalable if an external reference is applied to Pin 4. Input signals beyond this window trigger the OR pin and clamp digital outputs to full-scale codes.
Does AD9051BRS-2V support 3 V logic interfacing without level shifters?
Yes, AD9051BRS-2V supports direct 3 V logic interfacing: its ENCODE input is TTL-compatible (1.5 V threshold), and its digital outputs (D0–D9, OR) are CMOS with dedicated VDD pins (20, 22). Connecting Pins 20 and 22 to a 3 V supply configures all outputs for 3 V logic levels, eliminating need for external translators.
How does the BWSEL pin affect AD9051BRS-2V performance?
The BWSEL pin (Pin 5) selects input bandwidth: tied to VD it sets 50 MHz nominal bandwidth (optimized for lower noise), while left unconnected or grounded enables 130 MHz nominal bandwidth (optimized for wideband signal capture). This selection directly impacts SFDR and noise floor - confirmed in TPC 4 of the AD9051BRS-2V datasheet.
What is the latency and timing behavior of AD9051BRS-2V?
AD9051BRS-2V exhibits five-pipeline-stage latency. Output data (D9–D0) becomes valid one propagation delay (tPD) after the rising edge of the ENCODE signal. tPD is 4.5 ns typical at 25°C with 5 V VDD, and varies predictably with temperature and supply - documented in TPC 16 of the AD9051BRS-2V datasheet.
Can AD9051BRS-2V operate without its internal voltage reference?
Yes, AD9051BRS-2V can operate without the internal reference: the VREFOUT (Pin 3) and VREFIN (Pin 4) are separate nodes. To use an external reference, disconnect Pin 3 from Pin 4 and apply a stable 2.5 V source to Pin 4. The internal reference remains powered but unused, and the ADC full-scale range tracks the external reference within ±5% adjustment range.
