Product details
Overview
AD9245BCPZ-65 from Analog Devices is a 14-bit, 65 MSPS analog-to-digital converter (ADC) with single 3 V supply operation, differential input bandwidth up to 500 MHz, on-chip reference and sample-and-hold, and DNL of ±0.5 LSB. It delivers 72.7 dBc SNR and 83.0 dBc SFDR at 32.5 MHz input, targeting IF sampling in wireless receivers and medical ultrasound systems.
For engineers reviewing the AD9245BCPZ-65 datasheet, AD9245BCPZ-65 pinout, AD9245BCPZ-65 application, or AD9245BCPZ-65 equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternatives, and supply support for industrial and communications hardware development.
Technical Context
The AD9245BCPZ-65 employs a multistage differential pipelined architecture with output error correction logic to guarantee 14-bit accuracy and no missing codes across –40°C to +85°C. Its wide-bandwidth sample-and-hold amplifier supports both differential and single-ended analog inputs with user-selectable common-mode voltage and 1 Vp-p to 2 Vp-p input span.
A dedicated clock duty-cycle stabilizer (DCS) maintains performance across wide clock pulse width variations, while flexible digital output drivers support 2.5 V or 3.3 V logic families via separate DRVDD supply. The OTR (out-of-range) signal flags overflow conditions for real-time signal monitoring in high-dynamic-range applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - guarantees full-scale quantization with ≤1 LSB step size and no missing codes over temperature. |
| Sample Rate | 65 MSPS - enables Nyquist-limited digitization of signals up to 32.5 MHz without aliasing in baseband or IF sampling. |
| SNR / SFDR | 72.7 dBc / 83.0 dBc at 32.5 MHz - supports high-fidelity capture of narrowband RF/IF signals in WCDMA and CDMA-2000 receivers. |
| Power Consumption | 300 mW at 65 MSPS - balances performance and thermal budget for battery-powered or space-constrained instrumentation. |
| Differential Nonlinearity | ±0.5 LSB - ensures monotonic transfer function critical for closed-loop control and precision measurement systems. |
| Analog Input Bandwidth | 500 MHz - allows direct sampling of high-frequency IF stages without external amplification or filtering degradation. |
| Reference Options | Internal 1.0 V or 0.5 V reference, or external reference - simplifies system BOM and supports flexible gain scaling in multi-channel ADC arrays. |
Pinout & Package
The AD9245BCPZ-65 is housed in a 32-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle, optimized for thermal dissipation and high-frequency signal integrity. Soldering the exposed pad to the PCB ground plane is required for rated θJA = 32.5°C/W and reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock Input | Single-ended CMOS-compatible input controlling all conversion cycles; supports DCS for jitter resilience across duty cycle variation. |
| VIN+, VIN– | Differential Analog Input | High-impedance (7 kΩ), low-capacitance (7 pF) inputs accepting 1–2 Vp-p differential signals up to 500 MHz bandwidth. |
| D0–D13 | Parallel Digital Output | 14-bit straight binary or twos complement data bus; output levels configurable for 2.5 V or 3.3 V logic via DRVDD supply. |
| OTR | Overflow Indicator | Active-high flag signaling input exceeding selected full-scale range; used with MSB to distinguish high/low saturation events. |
| MODE | Format & DCS Control | Selects data format (offset binary/twos complement) and enables/disables clock duty-cycle stabilizer per Table 11. |
| SENSE, VREF, REFT, REFB | Reference Interface | Configures internal/external reference mode and sets reference voltage level (0.5 V or 1.0 V) for precise input scaling. |
| AVDD, AGND, DRVDD, DGND | Power & Ground | Separate analog/digital supplies minimize noise coupling; AVDD = 2.7–3.6 V, DRVDD = 2.25–3.6 V, mandatory decoupling required. |
Key Features
| Feature | Design Value |
|---|---|
| Single 3 V supply with independent DRVDD | Eliminates need for multiple voltage rails; supports mixed-signal SoC integration and reduces power supply complexity. |
| On-chip sample-and-hold with 500 MHz bandwidth | Enables direct IF sampling at 70 MHz without external amplifiers, preserving SNR and reducing component count. |
| Flexible analog input range (1–2 Vp-p) | Matches output swing of common RF mixers and IF amplifiers, avoiding external attenuation or gain stages. |
| Out-of-range (OTR) indicator with pipeline latency of 7 cycles | Provides deterministic timing for real-time clipping detection in spectrum analyzers and digital predistortion feedback loops. |
| Pin-compatible with AD9215/AD9235/AD9236 | Allows seamless migration from 10-bit to 14-bit resolution and 20–80 MSPS rates without PCB redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9246BCPZ-65 | 16-bit resolution, same 65 MSPS rate, higher 74.5 dBc SNR but 420 mW power consumption. | Used where ENOB > 12 bits is mandatory (e.g., MRI gradient control), not suitable for power-constrained designs. | Select AD9246BCPZ-65 only when 2-bit resolution uplift justifies +40% power and cost increase. |
| ADS5272IPFP | 12-bit, 65 MSPS, 70.5 dBc SNR, LVDS outputs, 250 mW power, QFN-64 package. | Targets multi-channel data acquisition with serialized outputs; lacks internal reference and DCS functionality. | Choose ADS5272IPFP for channel density > 8 and JESD204B interface requirements, not for single-channel IF sampling. |
Compared with AD9245BCPZ-65, AD9246BCPZ-65 trades higher resolution and SNR for increased power and cost, while ADS5272IPFP offers lower resolution and different interface architecture suited to scalable multi-ADC systems rather than standalone high-fidelity digitization.

FAQ
What is the maximum analog input frequency supported by the AD9245BCPZ-65?
The AD9245BCPZ-65 features a 500 MHz analog input bandwidth, enabling accurate digitization of signals up to that frequency. However, its usable Nyquist-limited input range is 0–32.5 MHz at 65 MSPS. Performance metrics like SNR and SFDR are specified up to 100 MHz input, confirming robust high-frequency response beyond the first Nyquist zone.
Does the AD9245BCPZ-65 require an external reference voltage?
No, the AD9245BCPZ-65 includes an on-chip reference generating either 0.5 V or 1.0 V, selectable via the SENSE pin. External reference operation is optional and supported through REFT/REFB pins for improved stability or custom scaling. Internal reference accuracy is ±35 mV at 1.0 V mode, sufficient for most IF sampling applications.
What is the purpose of the OTR pin on the AD9245BCPZ-65?
The OTR (Out-of-Range) pin on the AD9245BCPZ-65 is an active-high digital output indicating when the analog input exceeds the selected full-scale range. It operates with 7-cycle pipeline latency and pairs with the MSB to distinguish between high-overflow and low-overflow conditions, enabling real-time signal clipping detection in spectrum analyzers and digital predistortion systems.
Can the AD9245BCPZ-65 operate with a 2.5 V digital supply?
Yes, the AD9245BCPZ-65 supports a separate digital output driver supply (DRVDD) ranging from 2.25 V to 3.6 V. At DRVDD = 2.5 V, it delivers valid CMOS-level outputs: VOH ≥ 2.45 V at 0.5 mA load and VOL ≤ 0.2 V at 1.6 mA load. This allows direct interfacing with 2.5 V FPGAs or ASICs without level-shifting circuitry.
Is the AD9245BCPZ-65 pin-compatible with other members of the AD92xx family?
Yes, the AD9245BCPZ-65 is pin-compatible with the AD9215, AD9235, and AD9236, enabling straightforward migration from 10-bit to 14-bit resolution and from 20 MSPS to 80 MSPS sample rates. Pin mapping, power domains, and reference interface remain identical-only performance specifications and internal architecture differ across the family.
