16bit convertor range extends to 130Msample/s

A new 16bit, 130Msample/s A/D convertor from Linear Technology extends the company's leadership in high speed ADCs for the most demanding wideband low-noise signal-acquisition applications.

A new 16bit, 130Msample/s A/D convertor from Linear Technology extends the company's leadership in high speed ADCs for the most demanding wideband low-noise signal-acquisition applications.

The LTC2208 ADC addresses the key requirements for maximising performance of high sensitivity receivers and data acquisition systems.

The device's exceptional spurious free dynamic range (SFDR) performance of 100dBc, combined with 78dB signal to noise ratio (SNR), enable it to resolve low level signals in the presence of large interferers and blockers.

The LTC2208 is the fastest 16bit, high performance ADC on the market today.

The LTC2208 family innovates 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 100dBc for low level input signals.

The second feature is a digital output randomiser that dramatically reduces unwanted tones caused by digital feedback.

The flexible digital outputs can be run as CMOS or LVDS.

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 1.5V peak-peak.

This improves the distortion performance and power consumption of the driver with minimal impact on ADC noise performance.

The LTC2208 packages an extensive feature set in a 9 x 9mm QFN package delivering low power consumption at 1250mW without the need for heatsinking.

Most importantly, both the power consumption and total solution size with integrated bypass capacitance are less than half that of the nearest competitor.

Designed for ease of use, it requires only a single 3.3V supply for operation and comes with a clock duty cycle stabiliser for maintaining the ADC performance over varying duty cycles.

The LTC2208 can accept high frequency, wide dynamic range signals, offering a wide analogue input bandwidth of 700MHz.

The LTC2208 family includes speed grades of 130, 105, 80, 65, 40, 25 and 10Msample/s all with superior SFDR and SNR performance.

In addition to the 16bit parts, 14bit versions of this family are also available.

All devices are supported with demo boards for quick device evaluation.

Samples and demo boards for the LTC2208 are available now as well as production quantities for both commercial and industrial temperature grades and are competitively priced at $65 each in 1000-piece quantities.
