Product details

Overview

AD9214BRSZ-RL65 from Analog Devices is a 10-bit, 65 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 or 2 V_p-p input range-designed for battery-powered scopemeters and ultrasound front-ends requiring low power and compact size.

For engineers reviewing the AD9214BRSZ-RL65 datasheet, AD9214BRSZ-RL65 pinout, AD9214BRSZ-RL65 application, or AD9214BRSZ-RL65 equivalent, key selection considerations include its 65 MSPS sampling rate, 57 dB SNR at 39 MHz, 190 mW active power, 28-SSOP package, and dual data format (twos complement/offset binary) support.

Technical Context

The AD9214BRSZ-RL65 implements a bit-per-stage pipeline architecture with switch-capacitor techniques to deliver 10-bit resolution at 65 MSPS while maintaining 57 dB SNR at 39 MHz. Its differential analog input stage is internally biased at AVDD/3 and supports both ac- and dc-coupled inputs with 20 kΩ differential resistance and 5 pF capacitance.

It features fully TTL/CMOS-compatible ENCODE and digital outputs, separate DrVDD supply for 2.5 V/3.3 V logic interfacing, and configurable reference mode via REFSENSE pin-enabling either internal 1.25 V reference (REF output) or external 1.25 V ±5% reference (REF input).

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	10-bit-guarantees no missing codes across industrial temperature range (−40°C to +85°C).
Sampling Rate	65 MSPS-maximum conversion rate validated per specification; minimum usable rate is 20 MSPS.
SNR @ 39 MHz	57 dB at −0.5 dBFS-measured with 2 V_p-p input range; defines usable dynamic range for RF and ultrasound IF sampling.
Analog Bandwidth	300 MHz-supports wideband signal acquisition up to Nyquist frequency of 32.5 MHz without significant amplitude roll-off.
Power Consumption	190 mW at 65 MSPS-enables thermal management in handheld instruments; drops to 30 mW in power-down mode.
Input Range Option	Selectable 1 V_p-p or 2 V_p-p-configured via DFS/GAIN pin; 2 V_p-p improves noise immunity but trades off SFDR by ~3–5 dB.
Data Format	Twos complement or offset binary-selected via DFS/GAIN pin; determines MSB polarity and zero-scale mapping for downstream FPGA/DSP processing.

Pinout & Package

The AD9214BRSZ-RL65 is housed in a 28-lead SSOP (Shrink Small Outline Package), 5.6 mm × 10.2 mm body, 0.65 mm lead pitch, surface-mount compatible with industrial temperature range (−40°C to +85°C).

Pin/Terminal	Circuit Role	Design Meaning
OR (Pin 1)	Out-of-Range Indicator	CMOS output asserts HIGH when analog input exceeds full-scale range-enables real-time clipping detection without external comparator.
DFS/GAIN (Pin 2)	Data Format & Input Range Select	Configures twos complement/offset binary output and 1 V_p-p/2 V_p-p input swing via external connection to AVDD, AGND, REF, or floating.
REFSENSE (Pin 3)	Reference Mode Control	Connect to AGND for internal 1.25 V reference (REF = output); connect to AVDD for external 1.25 V reference (REF = input).
REF (Pin 4)	Reference I/O	Either supplies or accepts 1.25 V ±5% reference; requires 0.1 µF bypass capacitor to AGND regardless of mode.
AIN / AIN (Pins 9, 10)	Differential Analog Input	High-impedance buffered inputs with 20 kΩ differential resistance and 5 pF capacitance; internally biased at AVDD/3 for flexible ac/dc coupling.
ENCODE (Pin 13)	Sampling Clock Input	TTL/CMOS-compatible rising-edge-triggered clock; aperture jitter is 3 ps rms-critical for preserving SNR in high-frequency sampling.
PWRDN (Pin 14)	Power-Down Control	Logic HIGH places ADC in 30 mW sleep mode; outputs enter high-impedance state; recovery requires ~15 clock cycles.
D0–D9 (Pins 17–22, 25–28)	Digital Output Data Bus	CMOS outputs driven from separate DrVDD supply (2.5 V–3.6 V)-allows direct interface to 2.5 V or 3.3 V logic families without level shifters.

Key Features

Feature	Design Value
On-chip track-and-hold	Eliminates need for external sample-hold amplifier-reduces BOM count and layout complexity in portable test equipment.
Single 3.3 V supply (2.7–3.6 V)	Simplifies power design by removing dual-supply sequencing requirements; AVDD powers analog core, DrVDD powers digital outputs independently.
300 MHz analog input bandwidth	Supports direct sampling of IF signals up to 32.5 MHz (Nyquist) with minimal passband droop-ideal for cable reverse path and broadband wireless receivers.
190 mW at 65 MSPS	Enables thermally constrained designs such as hand-held scopemeters; power-down mode reduces consumption to 30 mW during idle intervals.
Configurable 1 V_p-p/2 V_p-p input range	Allows optimization for signal chain SNR (1 V_p-p) or robustness against gain drift and noise (2 V_p-p) without hardware change.

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
AD9215BRSZ-65	12-bit resolution, same 65 MSPS rate, higher 70 dB SNR at 10 MHz, 325 mW power, identical 28-SSOP package and pinout.	Used where higher resolution and SNR justify added power and cost-e.g., precision medical imaging or spectrum analyzers.	Select AD9215BRSZ-65 only if 12-bit depth and ≥65 dB SNR are required; AD9214BRSZ-RL65 remains optimal for cost- and power-sensitive 10-bit applications.
MAX1186ETL+	10-bit, 65 MSPS, 55 dB SNR at 10 MHz, 175 mW, 32-pin TQFN, different pinout and reference architecture (no internal ref).	Targeted at space-constrained consumer electronics; lacks on-chip reference and requires external REF buffer.	Choose MAX1186ETL+ only for ultra-small form factor designs accepting trade-offs in SNR and reference integration; AD9214BRSZ-RL65 offers superior ease-of-use with internal reference and proven industrial reliability.

Compared with AD9215BRSZ-65, AD9214BRSZ-RL65 delivers lower power and cost at 10-bit resolution; compared with MAX1186ETL+, it provides integrated reference and higher SNR at the expense of larger package size-making it the balanced choice for portable test and medical instrumentation.

FAQ

What is the maximum analog input frequency supported by the AD9214BRSZ-RL65?

The AD9214BRSZ-RL65 has a specified analog input bandwidth of 300 MHz, meaning it maintains flat frequency response up to that point. However, its usable Nyquist-limited input frequency is 32.5 MHz at 65 MSPS sampling. Performance metrics like SNR and SFDR are guaranteed up to 39 MHz input with −0.5 dBFS signal level, as verified in the datasheet's AC specifications table.

Does the AD9214BRSZ-RL65 require an external reference voltage?

No-the AD9214BRSZ-RL65 includes an internal 1.25 V reference that is enabled by connecting REFSENSE (Pin 3) to AGND. In that configuration, REF (Pin 4) becomes an output supplying the internal reference. An external reference is optional and only required when higher accuracy or temperature stability than the internal reference provides is needed.

How does the DFS/GAIN pin configure input range and data format on the AD9214BRSZ-RL65?

The DFS/GAIN pin (Pin 2) sets both parameters simultaneously: connection to AGND selects offset binary output and 1 V_p-p input range; connection to AVDD selects twos complement output and 1 V_p-p input; connection to REF selects twos complement output and 2 V_p-p input; leaving it floating selects offset binary output and 2 V_p-p input-as defined in Table 8 of the AD9214 datasheet Rev. E.

What is the power-down current consumption of the AD9214BRSZ-RL65?

When PWRDN (Pin 14) is asserted HIGH, the AD9214BRSZ-RL65 enters power-down mode with total supply current reduced to 10–15 mA (IAVDD), resulting in 30 mW total power consumption. Outputs go to high-impedance state, and the device requires approximately 15 clock cycles to stabilize and resume valid data output upon exit from power-down.

Can the AD9214BRSZ-RL65 interface directly with 2.5 V logic devices?

Yes-the AD9214BRSZ-RL65 features a dedicated DrVDD pin (Pins 16, 24) that powers only the digital output drivers. By supplying 2.5 V to DrVDD (with DGND as reference), all D0–D9 and OR outputs become fully compatible with 2.5 V CMOS/TTL logic families-eliminating the need for external level shifters in mixed-voltage systems.
