Product details
Overview
AD9245BCPZ-80 from Analog Devices is a 14-bit, 80 MSPS monolithic analog-to-digital converter (ADC) with single 3 V supply operation, differential input (500 MHz bandwidth), on-chip reference, and sample-and-hold amplifier. It delivers 72.7 dBc SNR at 40 MHz input and 83.0 dBc SFDR at Nyquist, targeting IF sampling in communications receivers and medical ultrasound systems.
For engineers reviewing the AD9245BCPZ-80 datasheet, AD9245BCPZ-80 pinout, AD9245BCPZ-80 application, or AD9245BCPZ-80 equivalent, key selection criteria include its 80 MSPS maximum conversion rate, ±0.5 LSB DNL, 366 mW power consumption at full speed, industrial temperature range (–40°C to +85°C), and LFCSP-32 package compatibility with AD9215/AD9235/AD9236.
Technical Context
The AD9245BCPZ-80 employs a multistage differential pipelined architecture with output error correction logic to guarantee 14-bit accuracy and no missing codes across temperature. Its patented sample-and-hold amplifier supports both differential and single-ended inputs up to 100 MHz analog bandwidth.
A dedicated clock duty-cycle stabilizer (DCS) maintains performance across wide clock pulse width variations, while the OTR (out-of-range) signal provides overflow detection synchronized to the pipeline latency of 7 cycles. Digital outputs support offset binary or twos complement format with configurable DRVDD (2.25 V to 3.6 V) for 2.5 V or 3.3 V logic interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - guarantees 16,384 discrete output codes with no missing codes over full temperature range. |
| Max Sample Rate | 80 MSPS - enables digitization of IF signals up to 40 MHz without aliasing under Nyquist criterion. |
| SNR @ 40 MHz | 72.7 dBc - defines minimum detectable signal level above quantization and thermal noise floor. |
| SFDR @ Nyquist | 83.0 dBc - determines dynamic range available before strongest spurious tone interferes with signal recovery. |
| Power @ 80 MSPS | 366 mW - total dissipation (AVDD + DRVDD) enabling battery-powered or thermally constrained designs. |
| Differential Nonlinearity | ±0.5 LSB - ensures monotonic transfer function critical for closed-loop control and precision measurement. |
| Analog Input Bandwidth | 500 MHz - supports wideband RF/IF sampling with minimal amplitude roll-off up to 100 MHz. |
| Aperture Jitter | 0.3 ps rms - limits sampling uncertainty-induced noise, especially critical above 10 MHz input frequencies. |
Pinout & Package
The AD9245BCPZ-80 is housed in a 32-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle, requiring soldering to PCB ground plane for thermal and reliability performance per Analog Devices recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock Input | Single-ended edge-triggered input controlling all internal conversion cycles; accepts 12.5 ns minimum period (80 MSPS). |
| VIN+, VIN– | Differential Analog Input | High-bandwidth (500 MHz) input pair supporting 1 Vp-p to 2 Vp-p range; common-mode adjustable via REFT/REFB. |
| D0–D13 | Parallel Digital Output | 14-bit straight binary or twos complement data bus; timing-critical outputs with 4.2 ns propagation delay (tPD). |
| OTR | Out-of-Range Indicator | Active-high flag signaling input exceeding selected span; used with MSB to distinguish high/low overflow conditions. |
| MODE | Data Format & DCS Control | Selects output coding (offset binary/twos complement) and enables/disables clock duty-cycle stabilizer. |
| SENSE, VREF, REFT, REFB | Reference Interface | Supports internal 1.0 V reference or external differential reference; SENSE pin configures reference mode. |
| AVDD, AGND, DRVDD, DGND | Power & Ground | Separate analog/digital supplies isolate noise; AVDD = 2.7–3.6 V, DRVDD = 2.25–3.6 V for flexible logic interfacing. |
| PDWN | Power-Down Control | Active-low input reducing power to 1.0 mW; wake-up time ≤7 ms with standard decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Single 3 V supply with isolated digital driver rail | Enables direct interface to 2.5 V or 3.3 V FPGAs/ASICs without level shifters, reducing BOM count and layout complexity. |
| Duty-cycle stabilizer (DCS) | Maintains full AC performance (SNR/SFDR) despite clock duty cycle variation from 30% to 70%, relaxing clock source requirements. |
| On-chip sample-and-hold with 500 MHz bandwidth | Allows accurate sampling of fast-rising IF signals (e.g., WCDMA burst envelopes) without external SHA circuitry. |
| Flexible analog input range (1–2 Vp-p) | Permits optimization of dynamic range versus noise floor by matching ADC span to signal chain output swing. |
| Guaranteed no missing codes over –40°C to +85°C | Eliminates calibration overhead in industrial and medical systems where deterministic linearity is mandatory. |

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-80 | 16-bit resolution, same 80 MSPS rate, higher 74.5 dBc SNR but 450 mW power at full speed. | Used where ENOB > 12 bits is mandatory (e.g., high-fidelity spectrum analysis), not suitable for power-constrained designs. | Select AD9246BCPZ-80 only when 16-bit linearity and SNR outweigh 23% higher power and cost. |
| ADS5463IPFP | Texas Instruments part: 13-bit, 500 MSPS, 65 dBc SNR at 100 MHz, requires dual 1.8 V/3.3 V supplies. | Targets ultra-wideband radar and electronic warfare with much higher sample rate but lower resolution and SNR. | Choose ADS5463IPFP for >100 MHz instantaneous bandwidth needs; avoid if 14-bit fidelity and 3 V single-supply simplicity are priorities. |
Compared with AD9245BCPZ-80, AD9246BCPZ-80 trades power efficiency for resolution headroom, while ADS5463IPFP sacrifices bit depth and supply simplicity for raw speed-making AD9245BCPZ-80 optimal for balanced IF sampling where 14-bit fidelity, 80 MSPS, and 3 V operation are jointly required.

FAQ
What is the maximum analog input frequency supported by the AD9245BCPZ-80?
The AD9245BCPZ-80 features a 500 MHz analog input bandwidth and has been characterized up to 100 MHz input frequency with 70.2 dBc SNR. Its effective full-power bandwidth exceeds 100 MHz, making it suitable for undersampled IF signals in communications receivers. Performance degrades gradually beyond 100 MHz due to analog front-end roll-off, not hard cutoff.
Does the AD9245BCPZ-80 require an external reference, or does it include an internal one?
The AD9245BCPZ-80 integrates an internal 1.0 V reference and supports external differential reference operation via REFT/REFB pins. Internal reference mode uses VREF, SENSE, and REFB; external mode bypasses internal reference and allows user-defined reference voltage. Both modes are fully supported in the AD9245BCPZ-80 datasheet Rev. E specifications.
Can the AD9245BCPZ-80 operate with a 2.5 V digital supply (DRVDD) while using 3 V for analog sections?
Yes, the AD9245BCPZ-80 explicitly supports independent analog (AVDD = 2.7–3.6 V) and digital driver (DRVDD = 2.25–3.6 V) supplies. Operating DRVDD at 2.5 V enables direct interfacing with 2.5 V FPGA I/O banks, while AVDD at 3.0 V ensures optimal analog performance-confirmed in Table 4 and Table 5 of the AD9245BCPZ-80 datasheet.
What is the pipeline latency of the AD9245BCPZ-80, and how does it affect system synchronization?
The AD9245BCPZ-80 has a fixed pipeline latency of 7 clock cycles from CLK edge to valid D0–D13 output. This deterministic delay enables precise timing alignment in synchronous systems such as digital downconverters or real-time spectrum analyzers. The latency is constant across all sample rates and input conditions, simplifying firmware-based phase compensation.
Is the AD9245BCPZ-80 pin-compatible with other members of the AD92xx family?
Yes, the AD9245BCPZ-80 is pin-compatible with AD9215, AD9235, and AD9236 per Product Highlights section of the datasheet. This allows drop-in replacement for resolution and speed upgrades (e.g., migrating from 10-bit/20 MSPS AD9215 to 14-bit/80 MSPS AD9245BCPZ-80) without PCB layout changes.
