The AD7492 is a 1.25MSPS, 16mW, internal REF and CLK, parallel ADC, suitable for VDD of 2.7V to 5.25V, with low power, wide input bandwidth, 70dB SNR and 2.5V internal reference.
The AD7492 family comprises 12‑bit successive‑approximation ADCs that operate from a single 2.7 V to 5.25 V supply. They provide high‑speed parallel conversion rates up to 1.25 MSPS (AD7492‑5) while maintaining low power dissipation, internal 2.5 V reference, and flexible power‑throughput management with partial and full sleep modes.
The device is supplied in 24‑lead SOIC and TSSOP packages, features a wide‑bandwidth track‑and‑hold amplifier (up to 10 MHz), and offers a full set of digital control pins for easy interfacing to microprocessors or DSPs.
