概述
Description
AD9240AS is Analog Devices’ 14‑bit, high‑speed ADC designed for RF, communications, radar, and instrumentation. The “AS” suffix identifies a specific grade/packaging variant of the AD9240 family; check the datasheet for exact temperature range and package.
Typical highlights:
- 14‑bit resolution with high conversion rate (on the order of ~100 MSPS class)
- Wide analog input bandwidth with differential inputs
- High‑speed parallel data outputs (often LVDS)
- On‑chip sample/hold, optional internal reference, and programmable gain
- Flexible clocking and control interface
- Optimized power/thermal performance across its speed range
Common applications:
- RF front‑ends and digital receivers
- Baseband/IF digitizers
- Test equipment and instrumentation
For exact specs (supply voltages, full‑scale range, SNDR, SINAD, temperature range, packaging), consult the AD9240AS datasheet and product page.

Features
Here are the typical features of the AD9240AS (high-level, concise):
- 14-bit resolution
- Dual, independently-referenced ADC cores
- High-speed sampling: tens of MSPS per channel (RF/IF suitable)
- High-speed serial outputs via JESD204B-compatible interface (LVDS)
- On-chip reference and input buffer
- Programmable full-scale, gain, and offset calibration
- Track-and-hold front end; differential or single-ended inputs with configurable common-mode
- Low-power operation with power-down modes
- Industrial temperature range (typical -40°C to +85°C)
- Available in compact packages (e.g., 48-pin LQFP/LFCSP)
Note: exact per-channel sample rate, power, and package options vary by revision and variant. Please refer to the AD9240AS datasheet for precise specifications.
