Norwood, Mass.—Analog Devices says its AD9254 14-bit, 150-MSPS analog-to-digital converter, with the best dynamic range of any competing ADC, consumes only 430 mW—a 50 percent reduction in power consumption over existing solutions.
Suited to WiMAX and picocell base station receivers, as well as ultrasound and handheld instrumentation equipment, the chip features 83-dBc SFDR (spurious-free dynamic range) at 70 MHz. In addition to achieving the highest SFDR in its class, the AD9254 has a signal-to-noise ratio of 72.7 dBFS at 70 MHz.
Its high sample rate also allows designers to realize the benefits of a lower noise floor and simplified AGC loop. The device is pin-compatible with the AD9246 and AD9233 ADCs and can be used with ADI's AD8352 driver IC.
