Product details
Overview
AD9214BRSZ-RL80 from Analog Devices is a 10-bit, 80 MSPS monolithic analog-to-digital converter with on-chip track-and-hold, single 3.3 V supply operation, 300 MHz analog bandwidth, and selectable 1 Vp-p/2 Vp-p input range - used in handheld scopemeters and broadband wireless receivers.
For engineers reviewing the AD9214BRSZ-RL80 datasheet, AD9214BRSZ-RL80 pinout, AD9214BRSZ-RL80 application, or AD9214BRSZ-RL80 equivalent, key selection criteria include SNR at 39 MHz (55 dB), power consumption (285 mW at full rate), ENOB (9.0 bits), differential nonlinearity (±0.5 LSB), and dual-supply flexibility (AVDD/DrVDD).
Technical Context
The AD9214BRSZ-RL80 implements a bit-per-stage pipeline architecture with switch-capacitor techniques to deliver 10-bit resolution at 80 MSPS, featuring internal error correction and overlapping stages for 7 MSBs plus a 3-bit flash sub-ADC. Its differential analog input buffer is internally biased at AVDD/3, supporting both ac- and dc-coupled inputs.
It integrates an on-chip 1.25 V reference (configurable via REFSENSE) and supports two data formats (twos complement or offset binary) and two gain modes (1 Vp-p or 2 Vp-p) controlled by the DFS/GAIN pin. The digital outputs are CMOS/TTL-compatible with separate DrVDD for logic-level flexibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - defines quantization step size of ~1 mV for 1 Vp-p input range, enabling precise digitization of medium-bandwidth signals. |
| Sampling Rate | 80 MSPS - supports Nyquist-limited signal capture up to 40 MHz, suitable for IF sampling in cable reverse path and ultrasound beamforming. |
| SNR @ 39 MHz | 55 dB - corresponds to ~9.0 effective bits (ENOB), sufficient for medium-fidelity waveform acquisition in portable test equipment. |
| Power Consumption | 285 mW at 80 MSPS - enables battery-powered operation when combined with 30 mW power-down mode for duty-cycled sensing. |
| Analog Bandwidth | 300 MHz - allows faithful digitization of fast-rising edges and wideband RF/IF signals without significant amplitude roll-off. |
| Differential Nonlinearity | ±0.5 LSB (typ) - ensures monotonic transfer function and absence of missing codes, critical for measurement accuracy in oscilloscopes. |
| Input Range Option | Selectable 1 Vp-p or 2 Vp-p - accommodates varying signal chain headroom requirements without external gain adjustment. |
Pinout & Package
The AD9214BRSZ-RL80 is housed in a 28-lead SSOP (Shrink Small Outline Package) with 0.65 mm lead pitch, rated for industrial temperature range (−40°C to +85°C) and optimized for compact, high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OR (Pin 1) | Out-of-Range Indicator | CMOS output asserts HIGH when analog input exceeds ±FS/2, enabling real-time clipping detection in digital oscilloscope front-ends. |
| DFS/GAIN (Pin 2) | Data Format & Input Range Select | Configures twos complement/offset binary output and 1 Vp-p/2 Vp-p input swing via external connection to AVDD, AGND, REF, or floating. |
| REFSENSE (Pin 3) | Reference Mode Control | Connect to AGND to enable internal 1.25 V reference (REF = output); connect to AVDD to disable internal ref and use external 1.25 V source. |
| REF (Pin 4) | Reference I/O | Supplies or accepts 1.25 V ±5% reference; requires 0.1 µF bypass capacitor to AGND regardless of configuration. |
| AIN / AIN (Pins 9–10) | Differential Analog Input | High-impedance (20 kΩ || 5 pF), internally biased at AVDD/3; supports ac/dc-coupled differential or single-ended drive with matched termination. |
| ENCODE (Pin 13) | Sampling Clock Input | TTL/CMOS-compatible rising-edge trigger; aperture jitter of 3 ps rms directly limits SNR at high input frequencies. |
| PWRDN (Pin 14) | Power-Down Control | Logic HIGH places ADC in 30 mW sleep mode; outputs enter high-impedance state; 15-cycle wake-up latency required before valid data. |
| D0–D9 (Pins 17–22, 25–28) | Digital Output Data Bus | CMOS outputs powered by DrVDD (2.5–3.6 V); support interfacing to 2.5 V or 3.3 V logic families without level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip track-and-hold with 300 MHz bandwidth | Eliminates need for external THA in most medium-speed applications, reducing BOM count and layout complexity. |
| Single 3.3 V analog supply (2.7–3.6 V) | Simplifies system power architecture by removing dedicated analog/digital rail separation requirements. |
| Separate DrVDD for digital outputs | Enables direct interface to mixed-voltage FPGA or ASIC I/O banks (2.5 V or 3.3 V) without external translators. |
| 1 Vp-p/2 Vp-p input range selection | Allows optimization of dynamic range versus noise floor depending on front-end amplifier output swing. |
| 30 mW power-down mode | Reduces average system power in burst-mode acquisition systems such as portable ultrasound or battery-operated spectrum analyzers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog-to-digital conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9215BCPZ-80 | 10-bit, 80 MSPS, 32-lead LFCSP package; lower power (200 mW), improved SNR (58 dB at 10 MHz), no internal reference - requires external 1.25 V source. | Better suited for space-constrained, thermally sensitive designs where external reference is already present. | Choose AD9215BCPZ-80 if board area and thermal budget are tighter, and external reference infrastructure exists. |
| ADS5270IPFP | 10-bit, 80 MSPS, 64-pin HTQFP; includes on-chip PLL, JESD204B interface, and higher supply rejection (PSRR = ±0.5 LSB/V vs. ±2 mV/V). | Targeted at multi-channel synchronized acquisition systems requiring deterministic latency and digital interface standardization. | Choose ADS5270IPFP for multi-ADC synchronization, FPGA JESD204B compatibility, or enhanced PSRR in noisy power environments. |
Compared with AD9214BRSZ-RL80, AD9215BCPZ-80 offers lower power and better SNR in a smaller package but removes integrated reference functionality, while ADS5270IPFP adds digital interface and synchronization features at the cost of larger footprint and higher complexity - making AD9214BRSZ-RL80 optimal for standalone, low-BOM-count, reference-integrated medium-speed digitization.

FAQ
What is the maximum sampling rate supported by the AD9214BRSZ-RL80?
The AD9214BRSZ-RL80 supports a maximum sampling rate of 80 MSPS, as confirmed in the Rev. E datasheet Table 4 under "Maximum Conversion Rate" for the AD9214-80 variant. This rate is fully characterized across the industrial temperature range (−40°C to +85°C) with guaranteed AC performance including SNR ≥55 dB at 39 MHz input.
Does the AD9214BRSZ-RL80 include an internal voltage reference?
Yes, the AD9214BRSZ-RL80 includes an internal 1.25 V reference, enabled when REFSENSE (Pin 3) is connected to AGND. In this configuration, REF (Pin 4) functions as a buffered reference output. The internal reference exhibits ±80 ppm/°C drift and supports 200 µA load, per Table 1 in the datasheet.
Can the AD9214BRSZ-RL80 operate with a 2.5 V digital I/O supply?
Yes, the AD9214BRSZ-RL80 supports a 2.5 V digital I/O supply via the DrVDD pin (Pins 16 and 24), which powers the D0–D9 and OR outputs. The digital outputs remain CMOS/TTL-compatible with logic thresholds defined relative to DrVDD, allowing direct interface to 2.5 V FPGA or ASIC I/O banks.
What is the analog input impedance of the AD9214BRSZ-RL80?
The AD9214BRSZ-RL80 presents a differential analog input impedance of 20 kΩ in parallel with 5 pF, as specified in Table 1 under "Differential Input Resistance" and "Differential Input Capacitance". Each input (AIN/AIN) is internally biased at AVDD/3, enabling flexible ac- or dc-coupled drive configurations.
How does the DFS/GAIN pin configure the AD9214BRSZ-RL80?
The DFS/GAIN pin (Pin 2) configures both data format and input range: tied to AVDD selects twos complement output with 1 Vp-p input; tied to AGND selects offset binary with 1 Vp-p; tied to REF selects twos complement with 2 Vp-p; left floating selects offset binary with 2 Vp-p, per Table 8 and Pin Function Descriptions in the datasheet.
