FEATURES

DESCRIPTION

•

ADS58B18: 11-Bit, 200MSPS

The ADS58B18/B19 are members of the ultralow

power ADS4xxx analog-to-digital converter (ADC)

family that features integrated analog buffers and

SNRBoost technology. The ADS58B18 and

ADS58B19 are 11-bit and 9-bit ADCs with sampling

rates up to 200MSPS and 250MSPS, respectively.

Innovative design techniques are used to achieve

high dynamic performance while consuming

extremely low power. The analog input pins have

buffers with constant performance and input

impedance across a wide frequency range. This

architecture makes these parts well-suited for

Ultralow Power:

–

Analog Power: 258mW at 200MSPS

I/O Power: 69mW (DDR LVDS, low LVDS

swing)

The ADS58B18 uses TI-proprietary SNRBoost

technology that can be used to overcome SNR

limitation as

a result of quantization noise for

bandwidths less than Nyquist (f_S/2).

–

–77.7dBFS SNR in 20MHz Bandwidth

Both devices have gain options that can be used to

improve SFDR performance at lower full-scale input

ranges, especially at very high input frequencies.

They also include a dc offset correction loop that can

be used to cancel the ADC offset. At lower sampling

rates, the ADC automatically operates at scaled-down

power with no loss in performance.

Output Interface:

–

Double Data Rate (DDR) LVDS with

Programmable Swing and Strength

–

Standard Swing: 350mV

Low Swing: 200mV

These devices support both double data rate (DDR)

low-voltage differential signaling (LVDS) and parallel

CMOS digital output interfaces. The low data rate of

the DDR LVDS interface (maximum 500Mbps) makes

it possible to use low-cost field-programmable gate

Default Strength: 100Ω Termination

low-swing LVDS mode that can be used to further

reduce the power consumption. The strength of the

LVDS output buffers can also be increased to support

50Ω differential termination.

Supports Low Input Clock Amplitude

Package: QFN-48 (7mm × 7mm)

The ADS58B18/B19 are both available in a compact

QFN-48 package and specified over the industrial

temperature range (–40°C to +85°C).
