AD7453 is a 12-bit high precision ADC that supports a sampling rate of 555kSPS and is packaged in SOT-23. The supply voltage range is 2.7V-5.25V.
The AD7453 is a 12‑bit, high‑speed, low‑power successive‑approximation ADC that operates from a single 2.7 V to 5.25 V supply. It provides pseudo‑differential analog inputs, a flexible serial interface (SPI/QSPI/MICROWIRE/DSP compatible), and no pipeline delays, making it suitable for battery‑powered and portable instrumentation.
Typical applications include transducer interfaces, data‑acquisition systems, and other battery‑powered or portable devices. The device features a 555 kSPS maximum throughput, low power dissipation (3.3 mW at 3 V), and a wide input bandwidth with 70 dB SINAD at 100 kHz.
