The AD9240 is a single-chip 14-bit, 10 MSPS analog-to-digital converter with features such as low power consumption and single supply.
The AD9240 is a 14‑bit, 10 MSPS analog‑to‑digital converter from Analog Devices that operates from a single +5 V supply. It integrates a sample‑and‑hold amplifier, on‑chip voltage reference, and programmable digital output drivers, offering low power dissipation and flexible input configurations for imaging, communications, medical, and data‑acquisition systems.
The datasheet provides complete electrical specifications, pin‑out descriptions, timing diagrams, and performance graphs such as SINAD, ENOB, and SFDR across frequency and clock‑rate ranges. It also includes thermal ratings, packaging dimensions for the 44‑lead MQFP, and guidelines for power‑/speed programmability via the BIAS pin.
| Resolution | 14 Bits |
|---|---|
| Maximum Conversion Rate | 10 MHz |
| Input Referred Noise (VREF=2.5 V) | 0.36 LSB rms |
| Power Consumption (typical) | 285 mW |
| Supply Voltage | +5 V single supply |
The AD9240 consumes about 285 mW typical (330 mW max).
With VREF = 2.5 V the input‑referred noise is 0.36 LSB rms.
The OTR (out‑of‑range) signal indicates an overflow condition.
The AD9240 operates from a single +5 V supply.
