Product details
Overview
AD9057BRSZ-60 from Analog Devices is an 8-bit, 60 MSPS monolithic analog-to-digital converter with 120 MHz full-power analog bandwidth, on-chip 2.5 V reference and track-and-hold, single 5 V supply operation, and TTL/CMOS-compatible encode input - optimized for QAM demodulator IF sampling and RGB video digitization.
For engineers reviewing the AD9057BRSZ-60 datasheet, AD9057BRSZ-60 pinout, AD9057BRSZ-60 application, or AD9057BRSZ-60 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-temperature operation (–40°C to +85°C), SSOP-20 package mapping, and two documented alternative ADCs for 60 MSPS sampling systems.
Technical Context
The AD9057BRSZ-60 employs a MagAmp/Flash hybrid architecture with three-pipeline-stage latency, enabling 60 MSPS conversion while maintaining 7.2-bit ENOB at 10.3 MHz input. Its internal track-and-hold captures analog signals on the rising edge of the TTL/CMOS encode clock, and offset binary coding ensures direct interface with FPGA or DSP logic.
It integrates a bandgap-based 2.5 V reference (±10 ppm/°C tempco) with 300 mA drive capability, supports both ac-coupled (via BIAS OUT 1 kΩ internal resistor) and dc-coupled analog inputs, and features independent 3 V/5 V digital I/O supply (VDD) decoupled from analog VD to minimize noise coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8-bit - provides 256 discrete output levels for medium-fidelity digitization in video and comms systems. |
| Max Conversion Rate | 60 MSPS - enables direct sampling of IF signals up to 30 MHz (Nyquist-limited) without undersampling constraints. |
| Analog Bandwidth | 120 MHz - supports accurate capture of fast transients in RGB pixel clocks and QAM constellation edges. |
| SINAD @ 10.3 MHz | 45 dB typical - corresponds to ~7.2 effective bits, sufficient for 8-bit system accuracy with margin. |
| Power Dissipation | 260 mW typical (VD = 5 V, VDD = 3 V) - balances speed and thermal load in compact PCB layouts. |
| Reference Voltage | 2.5 V ±10% - internally generated, stable enough to eliminate external reference components in most designs. |
| Operating Temp Range | –40°C to +85°C - qualified for industrial-grade embedded systems including baseband receivers and medical imaging front ends. |
Pinout & Package
AD9057BRSZ-60 is housed in a 20-lead shrink small outline package (SSOP, RS-20), 7.8 mm × 5.3 mm × 1.75 mm, JEDEC MO-150AE compliant, with gull-wing leads and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PWRDN) | Power-down control input | TTL/CMOS high activates <10 mW standby mode; outputs enter high-impedance state after 200 ns. |
| 2 (VREF OUT) | Internal reference output | 2.5 V ±10% source; requires 0.1 µF bypass to GND for low-noise ADC gain stability. |
| 3 (VREF IN) | ADC reference input | Accepts internal VREF OUT or external 2.5 V ±10%; sets full-scale range (1 Vp-p centered at VREF IN). |
| 4, 9, 16 (GND) | Analog/digital ground | Common return for analog signal path, digital outputs, and reference circuitry; star grounding recommended. |
| 5, 8 (VD) | Analog 5 V supply | Primary power for analog core and T/H; must be filtered separately from digital VDD to prevent SNR degradation. |
| 6 (BIAS OUT) | Internal bias resistor tap | Provides 1 kΩ path to VREF IN for ac-coupled inputs; eliminates need for external bias network. |
| 7 (AIN) | Analog input | Single-ended, 150 kΩ input impedance, 2 pF capacitance; accepts 1 Vp-p signal centered at VREF IN. |
| 10 (ENCODE) | Sampling clock input | Rising-edge triggered; 50% duty cycle preferred; min pulsewidth 5.5 ns (high) / 5.5 ns (low) at 60 MSPS. |
| 11–14, 17–20 (D0–D7) | Digital outputs | Offset binary format; driven from VDD (3 V or 5 V); tri-state in power-down mode. |
| 15 (VDD) | Digital I/O supply | Independent 3 V or 5 V rail; isolates digital switching noise from analog section; affects tPD (8.0–11.3 ns). |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold | Eliminates need for external TH circuitry, reducing board area and signal path complexity in IF sampling designs. |
| Integrated 2.5 V reference | Enables fully self-contained ADC operation with only one 5 V supply and encode clock - no external reference IC required. |
| 3 V / 5 V digital I/O compatibility | Allows direct interfacing with mixed-voltage FPGA or ASIC systems without level-shifting components. |
| Power-down mode (<10 mW) | Reduces system-level power during idle periods in burst-mode receivers or portable instrumentation. |
| Industrial temperature grade | Validated performance across –40°C to +85°C ensures reliability in uncontrolled environments like cable headends or factory-floor vision systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, 60 MSPS analog-to-digital converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9057BRSZ-40 | Lower max conversion rate (40 MSPS); identical pinout, package, and DC specs. | Not suitable for 60 MSPS IF sampling or 60 MHz pixel clock systems; usable only where encode rate ≤40 MSPS. | Select only if system timing budget allows reduced sampling rate and lower power (192 mW typical). |
| AD9057BRSZ-80 | Higher max conversion rate (80 MSPS); same SSOP-20 package and pinout; higher power (281 mW typical). | Supports wider Nyquist zones and higher IF frequencies; over-spec'd for 60 MSPS use cases. | Choose when future-proofing for >60 MSPS upgrades or when tighter aperture jitter (5 ps rms) is critical. |
Compared with AD9057BRSZ-40 and AD9057BRSZ-80, the AD9057BRSZ-60 delivers optimal balance of speed, power (260 mW), and cost for fixed 60 MSPS systems - avoiding unnecessary overhead of the -80 variant while meeting strict timing requirements the -40 cannot satisfy.

FAQ
What is the maximum analog input frequency supported by the AD9057BRSZ-60?
The AD9057BRSZ-60 has a full-power analog bandwidth of 120 MHz, meaning it maintains specified AC performance (e.g., SINAD ≥44.9 dB) for input frequencies up to 120 MHz. At 76 MHz input, it achieves 44.9 dB SINAD and 7.16 ENOB under 60 MSPS encode conditions - confirming usability well into VHF bands for undersampling applications.
Does the AD9057BRSZ-60 require an external reference voltage?
No, the AD9057BRSZ-60 does not require an external reference voltage. It includes an internal 2.5 V bandgap reference (VREF OUT) with ±10 ppm/°C temperature coefficient and 300 mA drive capability. This reference can be directly connected to VREF IN to set ADC gain and offset, eliminating external reference components in most designs.
What digital supply voltage options does the AD9057BRSZ-60 support for its D0–D7 outputs?
The AD9057BRSZ-60 supports dual digital I/O supply voltages: VDD may be operated at either 3 V or 5 V. When VDD = 3 V, digital outputs swing from 0.05 V to 2.95 V; at VDD = 5 V, they swing from 0.05 V to 4.95 V. This flexibility enables direct interfacing with both 3 V and 5 V logic families without level shifters.
How does the power-down function operate on the AD9057BRSZ-60?
The AD9057BRSZ-60 enters power-down mode when a logic high is applied to Pin 1 (PWRDN). Total power dissipation drops to <10 mW, and digital outputs transition to high-impedance state within 200 ns. The internal 2.5 V reference remains active to minimize wake-up latency; valid output data resumes three encode cycles after PWRDN returns low.
Is the AD9057BRSZ-60 pin-compatible with other members of the AD9057 family?
Yes, the AD9057BRSZ-60 is pin-compatible with AD9057BRSZ-40 and AD9057BRSZ-80. All three variants share identical 20-lead SSOP (RS-20) packaging, pin assignments, and DC electrical characteristics. Only the maximum encode rate (40/60/80 MSPS) and associated dynamic performance (e.g., tPD, power) differ - enabling drop-in replacement within the same PCB layout.
