Linear Technology’s LTC2206 is a 16-bit, 130 Ms/s ADC that addresses the key requirements for maximizing performance of high sensitivity receivers and data acquisition systems. The device’s spurious free dynamic range (SFDR) performance of 100 dBc, combined with 78 dB signal to noise ratio (SNR), enable it to resolve low level signals in the presence of large interferers and blockers. The LTC2208 family enhances ADC technology for digital receivers by incorporating two unique features that simplify receiver design and improve system performance. The first is an internal transparent dither circuit that improves the ADC’s spurious free dynamic range (SFDR) response well beyond 100 dBc for low level input signals. The second feature is a digital output randomizer that significantly reduces unwanted tones caused by digital feedback. The LT2208 also features a programmable gain amplifier (PGA) front end that eases the ADC driver output power requirements when driving the lower input range of 1.5 Vp-p. This improves the distortion performance and power consumption of the driver with minimal impact on ADC noise performance.
