Product details
Overview
AD80141BCPZ-140 from Analog Devices is a 12-bit, 125 MSPS analog-to-digital converter with 1.8 V analog supply operation, 650 MHz differential input bandwidth, and on-chip voltage reference and sample-and-hold amplifier-designed for IF sampling in communications receivers and ultrasound equipment.
For engineers reviewing the AD80141BCPZ-140 datasheet, AD80141BCPZ-140 pinout, AD80141BCPZ-140 application, or AD80141BCPZ-140 equivalent, this page delivers verified specifications including SNR = 69.5 dBc at 70 MHz input, SFDR = 85 dBc, DNL = ±0.15 LSB, 48-lead LFCSP package, and clock duty cycle stabilizer functionality.
Technical Context
The AD80141BCPZ-140 implements a multistage differential pipeline architecture with output error correction logic to guarantee 12-bit accuracy and no missing codes across −40°C to +85°C. Its patented differential sample-and-hold amplifier supports flexible analog input ranges (1 V p-p to 2 V p-p) and maintains performance up to 225 MHz input frequency.
A dedicated duty cycle stabilizer (DCS) ensures robust ADC performance across wide clock duty cycle variations, while the serial port interface enables configuration of data format (offset binary/Gray/twos complement), DCS enablement, power-down mode, and reference selection without requiring external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - guarantees monotonicity and no missing codes over full industrial temperature range. |
| Sampling Rate | 125 MSPS - supports Nyquist-sampled IF signals up to 62.5 MHz or undersampled RF bands beyond 170 MHz. |
| SNR / SFDR | 69.5 dBc / 85 dBc at 70 MHz input - enables high-fidelity digitization of CDMA-One and IMT-2000 channel waveforms. |
| Analog Supply | 1.8 V AVDD - reduces system power vs. legacy 3.3 V ADCs; compatible with modern low-voltage SoC domains. |
| Differential Input BW | 650 MHz - allows direct sampling of wideband IF stages without external amplification or filtering. |
| Power Consumption | 395 mW at 125 MSPS - optimized for battery-powered instruments and handheld scopemeters with thermal constraints. |
| Input Range Flexibility | 1 V p-p to 2 V p-p differential - simplifies front-end design across varying signal chain gain distributions. |
Pinout & Package
The AD80141BCPZ-140 is housed in a 48-lead LFCSP (CP-48-5) package with exposed thermal pad soldered to AGND for optimal thermal performance (θJA = 26.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts CMOS/LVDS/LVPECL; internal bias at 1.2 V enables interoperability with diverse clock sources. |
| VIN+, VIN− | Differential analog input | 650 MHz bandwidth supports direct IF sampling; input capacitance 8 pF per pin minimizes trace matching sensitivity. |
| D0–D11 | Parallel digital outputs | 12-bit offset binary/Gray/twos complement; DRVDD programmable from 1.8 V to 3.3 V for seamless FPGA/CPLD interfacing. |
| DCO | Data clock output | Synchronizes receiving logic to sampled data edges; eliminates setup/hold timing margin uncertainty in high-speed capture. |
| SDIO/DCS, SCLK/DFS, CSB | Serial port interface | 3-wire SPI-compatible control bus configures data format, DCS, power-down, and reference mode without external components. |
| RBIAS | Reference bias resistor connection | Requires 10 kΩ to AGND to set internal reference current; critical for stable 1.0 V reference accuracy (±5 mV typical). |
Key Features
| Feature | Design Value |
|---|---|
| Single 1.8 V analog supply | Eliminates dual-supply sequencing complexity and reduces BOM count vs. mixed-voltage ADCs. |

FAQ
What is the actual sampling rate specification for AD80141BCPZ-140?
The AD80141BCPZ-140 is specified at 125 MSPS maximum conversion rate with duty cycle stabilizer enabled, matching the AD9233BCPZ-125 datasheet performance. This rate supports full-scale sine wave inputs up to 170 MHz while maintaining 69.5 dBc SNR and 85 dBc SFDR at 70 MHz input frequency. The device guarantees no missing codes across its full operating temperature range.
Does AD80141BCPZ-140 support 1.8 V digital I/O interfaces?
Yes, AD80141BCPZ-140 supports 1.8 V digital I/O through its DRVDD supply pin, which accepts 1.8 V to 3.3 V. At DRVDD = 1.8 V, output high voltage is 1.75 V (at 0.5 mA load) and output low voltage is 0.2 V (at 1.6 mA load), ensuring reliable interfacing with 1.8 V FPGAs and ASICs without level-shifting circuitry.
What package type and thermal characteristics does AD80141BCPZ-140 use?
AD80141BCPZ-140 uses a 48-lead LFCSP (CP-48-5) package with exposed thermal pad connected to AGND. Its thermal resistance is θJA = 26.4°C/W and θJC = 2.4°C/W under standard 4-layer board conditions. Soldering the exposed paddle to the ground plane is mandatory to achieve rated thermal performance and long-term reliability.
Can AD80141BCPZ-140 operate with a single-ended analog input?
AD80141BCPZ-140 is designed for differential analog inputs (VIN+, VIN−) but supports single-ended operation via AC-coupled input with proper common-mode biasing using the CML pin. The internal sample-and-hold amplifier maintains 650 MHz bandwidth and 69.5 dBc SNR only when differential drive is implemented per layout guidelines in the AD9233 datasheet.
Is there a functional replacement for AD80141BCPZ-140 with full documentation?
Yes-AD9233BCPZ-125 is a functionally identical, pin-compatible, and fully documented replacement for AD80141BCPZ-140. It shares the same 12-bit/125 MSPS performance, 48-lead LFCSP package, and feature set, with complete datasheet (Rev. B), evaluation board support (AD9233-EBZ), and production availability through Analog Devices and authorized distributors.
