Product details

Overview

AD9214BRSZ-65 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/2 V_p-p input range - used in handheld scopemeters and ultrasound front-ends where low power and compact size are critical.

For engineers reviewing the AD9214BRSZ-65 datasheet, AD9214BRSZ-65 pinout, AD9214BRSZ-65 application, or AD9214BRSZ-65 equivalent, key selection factors include SNR at 39 MHz (57.1 dB), power consumption (190 mW at 65 MSPS), TTL/CMOS-compatible digital outputs, dual data format support (twos complement/offset binary), and industrial temperature range (−40°C to +85°C).

Technical Context

The AD9214BRSZ-65 implements a bit-per-stage pipeline architecture with switch-capacitor techniques, delivering 7 MSBs per stage plus a 3-bit flash sub-ADC, with built-in error correction and overlap for linearity optimization. Its differential analog input buffer is internally biased at AVDD/3, supporting both ac- and dc-coupled inputs.

It features fully independent analog (AVDD/AGND) and digital output (DrVDD/DGND) power domains, enabling logic-level flexibility (2.5 V or 3.3 V), while the ENCODE input accepts TTL/CMOS signals with 3 ps rms aperture jitter and 2 ns aperture delay - critical for time-domain fidelity in broadband acquisition systems.

Key Specifications

Sampling Rate	65 MSPS - supports Nyquist-limited baseband bandwidth up to ~32.5 MHz, suitable for cable reverse path and residential PLC applications.
SNR @ 39 MHz	57.1 dB (typ) - enables >9-bit effective resolution for RF IF sampling in ultrasound beamforming and broadband wireless receivers.
Analog Bandwidth	300 MHz - preserves high-frequency transients and harmonic content in fast-rising pulse capture (e.g., time-of-flight ultrasound).
Power Consumption	190 mW at 65 MSPS - reduces thermal load and extends battery life in hand-held instruments without compromising dynamic range.
Input Range Option	Selectable 1 V_p-p or 2 V_p-p - allows direct interface to low-voltage op-amps (e.g., AD8138) or higher-swing transformer-coupled sources without external attenuation.
Data Format	Twos complement or offset binary - simplifies FPGA or DSP interface logic by matching native arithmetic conventions of downstream processing blocks.

Pinout & Package

AD9214BRSZ-65 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, rated for −40°C to +85°C industrial operation.

Pin/Terminal	Circuit Role	Design Meaning
1 (OR)	Out-of-Range Indicator	CMOS output asserts HIGH when analog input exceeds ±FS/2 - enables real-time clipping detection without host processor overhead.
2 (DFS/GAIN)	Data Format & Input Range Select	Configures twos complement/offset binary output and 1 V_p-p/2 V_p-p full-scale via external connection to AVDD, AGND, REF, or floating - no configuration register required.
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 source (REF = input).
4 (REF)	Reference I/O	Provides or accepts 1.25 V ±5% reference - must be bypassed with 0.1 µF capacitor to AGND regardless of mode to suppress noise-induced quantization error.
5, 8, 11 (AGND)	Analog Ground	Dedicated low-noise return path for analog circuitry - must be isolated from DGND except at single-point star ground to prevent digital switching noise coupling.
6, 7, 12 (AVDD)	Analog Power Supply	2.7 V to 3.6 V supply powering track-and-hold, comparator array, and internal timing - requires local 0.1 µF + 10 µF ceramic decoupling.
9, 10 (AIN+, AIN−)	Differential Analog Input	High-impedance (20 kΩ \|\| 5 pF) differential pair with common-mode bias at AVDD/3 - supports single-ended operation if AIN− is terminated to AVDD/3.
13 (ENCODE)	Sampling Clock Input	TTL/CMOS-compatible rising-edge-triggered clock - 3 ps rms jitter tolerance ensures <0.1 LSB degradation in SNR at 39 MHz input.
14 (PWRDN)	Power-Down Control	Logic HIGH places ADC in 30 mW sleep mode with digital outputs in high-impedance state; recovery requires ~15 clock cycles before valid data.
15, 23 (DGND)	Digital Output Ground	Return path for D0–D9 and OR outputs - must be routed separately from AGND and joined only at system-level ground plane.
16, 24 (DrVDD)	Digital Output Driver Supply	2.7 V to 3.6 V supply setting logic swing level - enables direct interfacing to 2.5 V or 3.3 V FPGAs/ASICs without level shifters.
17–22, 25–28 (D0–D9)	Parallel Digital Outputs	CMOS-compatible 10-bit parallel bus (LSB = D0, MSB = D9) with 5-clock-cycle pipeline latency - supports synchronous latch capture in FPGA fabric.

Key Features

Feature	Design Value
On-chip track-and-hold	Eliminates need for external THA, reducing BOM count and board area in space-constrained portable instruments.
Integrated 1.25 V reference	Enables fully self-contained operation with only one external 0.1 µF bypass cap - cuts reference design time and improves supply noise immunity.
Separate DrVDD supply	Allows independent scaling of digital output voltage to match downstream logic (2.5 V or 3.3 V), avoiding level-shifter ICs and associated timing skew.
30 mW power-down mode	Reduces idle power by >84% versus active mode - essential for battery-operated devices requiring intermittent acquisition bursts.
Dual analog input range	Hardware-selectable 1 V_p-p/2 V_p-p full-scale accommodates diverse sensor/interface amplifier outputs without redesigning front-end gain stages.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD9215BCPZ-80	80 MSPS sampling rate, 10-bit resolution, same 28-lead LFCSP package but lower power (155 mW), slightly reduced SNR (55.0 dB @ 39 MHz).	Better suited for higher-bandwidth IF sampling where 80 MSPS enables wider Nyquist zone, but less optimal for strict 65 MSPS timing-critical designs.	Select AD9215BCPZ-80 only if system requires ≥80 MSPS and can accept 2.1 dB SNR trade-off; not drop-in due to different package and thermal profile.
ADS5271IPFP	10-bit, 65 MSPS, 48-pin HTQFP, 1.8 V analog supply, 700 mW power, 59.5 dB SNR @ 39 MHz, JESD204B serial output.	Targets high-channel-count systems needing serialized data transport and lower supply voltage, but consumes >3.6× more power and requires complex serializer interface.	Choose ADS5271IPFP only for multi-channel synchronized acquisition with FPGA JESD204B receiver; incompatible pinout and power architecture preclude direct replacement.

Compared with AD9214BRSZ-65, AD9215BCPZ-80 offers higher speed at lower power but reduced noise performance and different packaging, while ADS5271IPFP provides superior SNR and serial interface at significantly higher power and layout complexity - making AD9214BRSZ-65 the optimal balance for cost-sensitive, low-power, parallel-output embedded digitizers.

FAQ

What is the maximum analog input frequency supported by the AD9214BRSZ-65?

The AD9214BRSZ-65 has a 300 MHz analog input bandwidth, meaning it can accurately digitize signals with frequency content up to 300 MHz before significant amplitude roll-off occurs. However, its 65 MSPS sampling rate limits the Nyquist bandwidth to 32.5 MHz; signals above this will alias unless filtered. The 300 MHz bandwidth ensures minimal phase/gain distortion within the first Nyquist zone and supports undersampling applications with proper anti-alias filtering.

Does the AD9214BRSZ-65 require an external reference voltage?

No - the AD9214BRSZ-65 includes an internal 1.25 V reference that is enabled by connecting REFSENSE (Pin 3) to AGND. In that configuration, REF (Pin 4) becomes a buffered output of the internal reference and must be bypassed with a 0.1 µF capacitor to AGND. An external reference is optional and only needed when higher accuracy or temperature stability is required beyond the internal reference's ±80 ppm/°C drift.

How does the DFS/GAIN pin configure input range and data format on the AD9214BRSZ-65?

The DFS/GAIN pin (Pin 2) determines both analog input range and output data coding. Connecting it to AVDD selects twos complement format with 1 V_p-p input range; to AGND selects offset binary with 1 V_p-p; to REF selects twos complement with 2 V_p-p; and leaving it floating selects offset binary with 2 V_p-p. This hardware-based configuration eliminates firmware dependencies and ensures deterministic behavior at power-up.

What is the power-down current consumption of the AD9214BRSZ-65?

In power-down mode (PWRDN = HIGH), the AD9214BRSZ-65 draws 10 mA typical from AVDD at 3.0 V, resulting in 30 mW total power consumption. During this state, the analog core and digital output drivers are disabled, and all digital outputs enter high-impedance. Recovery to valid data output requires approximately 15 encode clock cycles after PWRDN returns LOW.

Can the AD9214BRSZ-65 interface directly with a 2.5 V FPGA I/O bank?

Yes - the AD9214BRSZ-65 supports direct interfacing with 2.5 V logic through its dedicated DrVDD supply pin (Pin 16/24). By applying 2.5 V to DrVDD and referencing DGND, the D0–D9 and OR outputs swing between 0 V and 2.5 V with TTL/CMOS-compatible thresholds, eliminating the need for external level shifters and preserving timing margins in high-speed parallel capture.
