DESCRIPTION

ADS62C17 is a dual channel 11-bit, 200 MSPS A/D converter that combines high dynamic performance and low

power consumption in a compact 64 QFN package. This makes it well-suited for multi-carrier, wide band-width

communications applications.

ADS62C17 uses TI-proprietary SNRBoost technology that can be used to overcome SNR limitation due to

quantization noise for bandwidths less than Nyquist (Fs/2). It includes several useful and commonly used digital

functions such as ADC offset correction, gain (0 to 6 dB in steps of 0.5 dB) and gain tuning (in fine steps of 0.001

dB).

The gain option can be used to improve SFDR performance at lower full-scale input ranges. Using the gain

tuning capability, each channel’s gain can be set independently to improve channel-to-channel gain matching.

The device also includes a dc offset correction loop that can be used to cancel the ADC offset.

Both DDR LVDS (Double Data Rate) and parallel CMOS digital output interfaces are available. It includes

internal references while the traditional reference pins and associated decoupling capacitors have been

eliminated. Nevertheless, the device can also be driven with an external reference.

The device is specified over the industrial temperature range (–40°C to 85°C).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
