Product details
Overview
AD9245BCP-80 from Analog Devices is a monolithic 14-bit, 80 MSPS analog-to-digital converter (ADC) with single 3 V supply operation, differential input (500 MHz bandwidth), on-chip reference and sample-and-hold, and clock duty-cycle stabilizer - used in IF sampling receivers, spectrum analyzers, and medical ultrasound systems.
For engineers reviewing the AD9245BCP-80 datasheet, AD9245BCP-80 pinout, AD9245BCP-80 application, or AD9245BCP-80 equivalent, this page delivers verified specs including SNR = 72.7 dBc at 40 MHz, DNL = ±0.5 LSB, 32-lead LFCSP package, 366 mW power at 80 MSPS, and OTR overflow detection for real-time signal integrity monitoring.
Technical Context
The AD9245BCP-80 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 patented sample-and-hold amplifier supports both differential and single-ended inputs up to 100 MHz analog bandwidth.
It integrates a clock duty-cycle stabilizer (DCS) that maintains performance over wide input duty-cycle variations, and provides flexible digital output formatting (offset binary or twos complement) with separate DRVDD supply (2.25 V to 3.6 V) for 2.5 V/3.3 V logic compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - guarantees full-scale quantization with 16,384 discrete levels and no missing codes over temperature. |
| 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 - ensures high-fidelity capture of narrowband RF/IF signals in communications receivers. |
| Power @ 80 MSPS | 366 mW - low power enables use in battery-powered scopemeters and portable spectrum analyzers. |
| Differential Nonlinearity | ±0.5 LSB - preserves signal fidelity in precision imaging and medical ultrasound beamforming. |
| Input Bandwidth | 500 MHz - supports wideband analog input conditioning without external amplification roll-off. |
| Aperture Jitter | 0.3 ps rms - minimizes sampling uncertainty for high-frequency signal reconstruction. |
Pinout & Package
The AD9245BCP-80 is housed in a 32-lead LFCSP (Lead Frame Chip Scale Package) with exposed thermal pad, specified for industrial temperature range (–40°C to +85°C). The exposed paddle must be soldered to the PCB ground plane for optimal thermal performance and solder joint reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock Input | Single-ended CMOS-compatible input controlling all conversion cycles; supports DCS for jitter resilience. |
| VIN+, VIN– | Differential Analog Input | High-bandwidth (500 MHz) input pair accepting 1 Vp-p to 2 Vp-p range with 7 pF effective capacitance. |
| D0–D13 | Parallel Digital Output | 14-bit straight binary or twos complement data bus; outputs referenced to DRVDD (2.5 V or 3.3 V). |
| OTR | Out-of-Range Indicator | Active-high flag signaling overflow beyond selected input span; used with MSB for signed overflow detection. |
| MODE | Data Format & DCS Control | Selects offset binary/twos complement output and enables/disables clock duty-cycle stabilizer. |
| SENSE, VREF, REFT, REFB | Reference Interface | Supports internal 1.0 V/0.5 V reference or external differential reference; SENSE selects mode. |
| AVDD, AGND | Analog Power/Ground | 3.0 V ±0.3 V analog supply; dual AGND pins reduce ground bounce in high-speed sampling. |
| DRVDD, DGND | Digital Output Supply/Ground | Independent 2.5 V or 3.3 V driver supply enabling mixed-voltage system interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Single 3 V supply with separate DRVDD | Enables interoperability with 2.5 V FPGA I/O banks while maintaining analog performance integrity. |
| Duty-cycle stabilizer (DCS) | Compensates for clock asymmetry without degrading SNR/SFDR - critical for low-jitter clock sources. |
| No missing codes guaranteed | Ensures monotonicity and eliminates code gaps in closed-loop control or calibration applications. |
| Flexible analog input range | 1 Vp-p or 2 Vp-p selection via VREF configuration - simplifies front-end gain staging across signal chains. |
| On-chip sample-and-hold (SHA) | Eliminates need for external track-and-hold; supports multiplexed inputs and >Nyquist sampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9246BCP-80 | 16-bit resolution, same 80 MSPS rate, higher SNR (74.5 dBc), but 450 mW power and 48-lead LFCSP package. | Used where ENOB >12 bits required (e.g., MRI gradient control), not suitable for space-constrained 32-pin layouts. | Select AD9246BCP-80 only when 16-bit precision justifies larger footprint and 23% higher power. |
| ADS5272IPFP | 12-bit, 80 MSPS, 32-lead QFP, 300 mW, no integrated reference, requires external REF buffer and clock conditioner. | Targeted at cost-sensitive industrial DAQ where 12-bit resolution suffices and board area allows discrete support components. | Choose ADS5272IPFP if BOM cost reduction outweighs loss of on-chip reference and increased layout complexity. |
Compared with AD9245BCP-80, AD9246BCP-80 trades higher resolution and SNR for greater power and package size, while ADS5272IPFP reduces cost and power at the expense of integration and linearity - making AD9245BCP-80 the optimal balance of precision, integration, and thermal efficiency for portable and IF-sampling designs.

FAQ
What is the maximum analog input frequency supported by the AD9245BCP-80?
The AD9245BCP-80 features a 500 MHz analog input bandwidth and maintains 72.7 dBc SNR at 40 MHz input frequency. While usable beyond Nyquist for undersampling, its full-power bandwidth supports accurate digitization of signals up to 100 MHz per the SHA specification - confirmed in the Product Highlights section of the Rev. E datasheet.
Does the AD9245BCP-80 require an external reference voltage?
No - the AD9245BCP-80 includes an on-chip 1.0 V or 0.5 V reference selectable via the SENSE pin. External reference operation is optional and supported through REFT/REFB pins, but internal reference usage eliminates external component count and improves system-level accuracy stability for the AD9245BCP-80.
What is the purpose of the OTR pin on the AD9245BCP-80?
The OTR (Out-of-Range) pin on the AD9245BCP-80 is an active-high indicator that asserts when the analog input exceeds the selected full-scale range. Used with the MSB, it distinguishes between positive and negative overflow conditions - enabling real-time clipping detection and adaptive gain control in the AD9245BCP-80 signal chain.
Can the AD9245BCP-80 operate with a 2.5 V digital supply?
Yes - the AD9245BCP-80 supports DRVDD from 2.25 V to 3.6 V, and its digital outputs are fully specified at 2.5 V (IOH = 0.5 mA yields 2.45 V high-level output). This allows direct interfacing with 2.5 V FPGA or ASIC I/O banks without level-shifting, as documented in Table 5 of the AD9245BCP-80 datasheet.
Is the AD9245BCP-80 pin-compatible with other members of the AD9245 family?
Yes - all AD9245 variants (BCP-20/40/65/80) share identical 32-lead LFCSP pinout and footprint. The AD9245BCP-80 is also pin-compatible with AD9215, AD9235, and AD9236, enabling hardware reuse across 10-bit to 14-bit, 20 MSPS to 80 MSPS migration paths per Product Highlights Section 3.
