Product details

Overview

AD9214BRS-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 V_p-p/2 V_p-p input range - used in handheld scopemeters and broadband wireless receivers for high-fidelity digitization of IF/RF signals.

For engineers reviewing the AD9214BRS-RL80 datasheet, AD9214BRS-RL80 pinout, AD9214BRS-RL80 application, or AD9214BRS-RL80 equivalent, this page delivers verified specs including SNR = 55.0 dB at 39 MHz (–0.5 dBFS), power consumption = 285 mW at full rate, pipeline delay = 5 clock cycles, ENOB = 9.0 bits at 10 MHz, and TTL/CMOS-compatible digital outputs with separate DrVDD rail.

Technical Context

The AD9214BRS-RL80 implements a bit-per-stage pipeline architecture with switch-capacitor techniques to resolve 7 MSBs per stage and drive a 3-bit flash sub-ADC, enabling 80 MSPS conversion with built-in error correction and overlap between stages. Its differential analog input buffer is internally biased at AVDD/3, supporting both ac- and dc-coupled inputs while maintaining common-mode rejection.

It integrates an on-chip reference (1.25 V nominal) configurable via REFSENSE pin, supports twos complement or offset binary output formats, and features a dedicated PWRDN pin that reduces power to 30 mW in sleep mode with high-impedance digital outputs - all within a 28-SSOP package rated for –40°C to +85°C industrial operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	10-bit quantization depth, delivering 1024 discrete output codes for precise amplitude representation.
Sampling Rate	80 MSPS maximum encode rate - supports Nyquist-limited signal capture up to 40 MHz without aliasing.
SNR @ 39 MHz	55.0 dB typical (–0.5 dBFS input) - defines usable dynamic range for medium-frequency IF sampling.
Analog Bandwidth	300 MHz - enables faithful digitization of wideband RF/IF signals without significant amplitude roll-off.
Power Consumption	285 mW at 80 MSPS - balances speed and thermal budget for portable and space-constrained systems.
Input Range Option	Selectable 1 V_p-p or 2 V_p-p differential swing via DFS/GAIN pin - matches source signal level without external gain staging.
Pipeline Delay	5 clock cycles - determines deterministic latency between sample acquisition and valid D0–D9 output.
Reference	On-chip 1.25 V ±5% reference (REFSENSE = AGND) or external 1.25 V input (REFSENSE = AVDD) - eliminates need for external reference IC in most designs.

Pinout & Package

AD9214BRS-RL80 is housed in a 28-lead SSOP (Shrink Small Outline Package) with 0.65 mm lead pitch, specified for industrial temperature range (–40°C to +85°C) and RoHS-compliant surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 (OR)	Out-of-Range Indicator	CMOS output asserts HIGH when AIN exceeds full-scale range - enables real-time clipping detection without host processor overhead.
2 (DFS/GAIN)	Data Format & Input Range Select	Configures output coding (twos complement/offset binary) and analog input swing (1 V_p-p/2 V_p-p) via external connection to AVDD, AGND, REF, or floating.
3 (REFSENSE)	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 on REF pin.
4 (REF)	Reference Input/Output	Delivers or accepts 1.25 V ±5% reference - must be bypassed to AGND with 0.1 µF capacitor regardless of configuration.
5, 8, 11 (AGND)	Analog Ground	Dedicated low-noise ground return for analog circuitry - must be isolated from DGND except at single-point star ground.
6, 7, 12 (AVDD)	Analog Power Supply	Single 2.7–3.6 V rail powering analog core, track/hold, and internal timing - requires local 0.1 µF + 10 µF decoupling.
9, 10 (AIN, AIN)	Differential Analog Inputs	High-impedance (20 kΩ \|\| 5 pF), internally biased at AVDD/3 - accept ac- or dc-coupled signals; AIN may be left open in single-ended mode.
13 (ENCODE)	Sampling Clock Input	TTL/CMOS-compatible rising-edge-triggered clock - jitter < 3 ps rms ensures minimal aperture uncertainty at 80 MSPS.
14 (PWRDN)	Power-Down Control	Logic HIGH places ADC in 30 mW sleep mode with digital outputs in high-Z state; recovery requires ~15 clocks to valid data.
15, 23 (DGND)	Digital Output Ground	Separate ground for CMOS output drivers - minimizes digital switching noise coupling into analog section.
16, 24 (DrVDD)	Digital Output Driver Supply	Adjustable 2.7–3.6 V rail setting logic threshold for D0–D9 outputs - supports interfacing with 2.5 V or 3.3 V downstream logic.
17–22, 25–28 (D0–D9)	Digital Data Outputs	CMOS-compatible parallel outputs (D0 LSB to D9 MSB) - require series termination (~100 Ω) near device to suppress reflections and EMI.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD9215BCPZ-80	12-bit resolution, same 80 MSPS rate, 3.3 V supply, but higher 350 mW power and 65 dB SNR @ 39 MHz.	Better dynamic range for demanding IF sampling; larger 32-lead LFCSP package vs. AD9214BRS-RL80's 28-SSOP.	Choose AD9215BCPZ-80 when 12-bit resolution and improved SFDR outweigh size and power constraints.
ADS5271IPFP	10-bit, 80 MSPS, but uses 1.8 V analog supply, LVDS outputs, and consumes only 210 mW - no integrated reference.	Requires external reference and level-shifting for CMOS interface; optimized for low-voltage, high-density multichannel systems.	Choose ADS5271IPFP when system-level power budget is critical and LVDS serialization is acceptable.

Compared with AD9215BCPZ-80 and ADS5271IPFP, AD9214BRS-RL80 offers the smallest footprint (28-SSOP), lowest cost, and highest integration (on-chip reference, track/hold, dual input range) - making it optimal for cost-sensitive, space-constrained, single-channel digitizers where 10-bit performance suffices.

FAQ

What is the maximum analog input frequency supported by the AD9214BRS-RL80?

The AD9214BRS-RL80 has a 300 MHz analog bandwidth, meaning it can accurately digitize signals up to approximately 300 MHz before –3 dB attenuation occurs. However, due to Nyquist criteria, its 80 MSPS sampling rate limits usable input frequencies to ≤40 MHz for unaliased baseband sampling. For undersampling applications, higher IF frequencies (e.g., 70 MHz) are supported with appropriate anti-alias filtering and system-level jitter control.

Does the AD9214BRS-RL80 require an external reference voltage?

No - the AD9214BRS-RL80 includes an on-chip 1.25 V reference that is enabled by connecting REFSENSE (Pin 3) to AGND. In that configuration, REF (Pin 4) becomes a reference output. An external 1.25 V ±5% reference is only required when REFSENSE is tied to AVDD, which disables the internal reference. Both configurations mandate a 0.1 µF bypass capacitor from REF to AGND.

How does the DFS/GAIN pin configure input range and data format on the AD9214BRS-RL80?

The DFS/GAIN pin (Pin 2) selects both analog input range and output coding: tied to AGND → 1 V_p-p range + offset binary; tied to AVDD → 1 V_p-p range + twos complement; tied to REF → 2 V_p-p range + twos complement; left floating → 2 V_p-p range + offset binary. This single-pin flexibility eliminates external configuration logic in most signal chain designs.

What is the power consumption of the AD9214BRS-RL80 during normal operation and power-down mode?

At 80 MSPS with full-scale input, the AD9214BRS-RL80 consumes 285 mW total (105 mA from AVDD and ~60 mA from DrVDD). In power-down mode (PWRDN = HIGH), current drops to 10–15 mA on AVDD, reducing total power to 30 mW. Recovery to valid output data takes approximately 15 clock cycles after exiting power-down.

Can the AD9214BRS-RL80 interface directly with a 2.5 V FPGA I/O bank?

Yes - the AD9214BRS-RL80 provides a dedicated DrVDD pin (Pins 16, 24) that powers only the D0–D9 digital outputs. By supplying 2.5 V to DrVDD (with DGND return), the outputs swing between 0 V and 2.5 V, meeting standard 2.5 V CMOS logic thresholds. Series termination resistors (~100 Ω) placed near the AD9214BRS-RL80 are still required to prevent signal integrity issues.
