16-bit, 160-Msps A/D converter delivers 77dB SNR

Milpitas, Calif.—Linear Technology Corp. has launched the LTC2209, a 16-bit, 160-Msps A/D converter for leading-edge communications equipment and instrumentation applications.

The LTC2209 extends the sampling frequency of the LTC2208 family, offering a pin-compatible upgrade path for existing designs. The LTC2209 has signal to noise ratio (SNR) performance of 77.1dB and spurious free dynamic range (SFDR) of 100dB at baseband, consuming 1450mW from a 3.3V supply.

The LTC2209 has two key features that simplify receiver design and improve system performance. The first is an internal transparent dither circuit that improves the ADC's SFDR response beyond 100dBc for low-level input signals. The second feature is a digital output randomizer that reduces unwanted tones caused by digital feedback. The flexible digital outputs can be run as CMOS or LVDS.

The LTC2209 family includes speed grades of 160Msps, 130Msps, 105Msps, 80Msps, 65Msps, 40Msps, 25Msps and 10Msps. In addition to the 16-bit LTC2209, the pin-compatible LTC2209-14 14-bit version will also be available.

Pricing: $72.50 each in 1,000-piece quantities.
Availability: Today in both commercial and industrial temperature grades.
