The AD9243 is a 14-bit, 3.0MSPS analog-to-digital converter that consumes only 110mW of power and is fully integrated on a single chip in a 44-lead MQFP package.
The AD9243 provides a complete single‑chip 14‑bit ADC solution in a 44‑lead MQFP package. It operates from a single +5 V supply and consumes only about 110 mW, offering low power dissipation while delivering excellent DC and AC performance. The device features an on‑chip sample‑and‑hold amplifier, programmable voltage reference, and digital output error‑correction logic, guaranteeing no missing codes across temperature.
Key specifications include a maximum conversion rate of 3 MHz, input‑referred noise as low as 0.36 LSB rms, and flexible analog input spans of 2 V p‑p (VREF = 1 V) to 5 V p‑p (VREF = 2.5 V). Digital outputs can be configured for both +3 V and +5 V CMOS logic families, and an out‑of‑range indicator signals overflow conditions.
