3 Description
The ADC3661, ADC3662, and ADC3663 (ADC366x)
family of devices are low-noise, ultra-low power, 16-
bit, 10-MSPS to 65-MSPS, high-speed, dual-channel,
analog-to-digital converters (ADCs). Designed for low
noise performance, these devices deliver a noise
spectral density of –158 dBFS/Hz combined with
great linearity and dynamic range. The ADC366x
offers good dc precision together with IF sampling
support making these devices suitable for a wide
range of applications. High-speed control loops
benefit from the short latency as low as only 1 clock
cycle. The ADC consumes only 94 mW/ch at 65
MSPS and power consumption that scales well with
lower sampling rates.
The ADC366x uses a serial LVDS (SLVDS) interface
to output the data. The devices support a two-lane,
a one-lane and a half-lane option. These devices are
a pin-to-pin compatible family with 16-bit and 18-bit
resolution and different speed grades. The devices
come in a 40-pint QFN package (5 x 5 mm), and
supports the extended industrial temperature range of
–40°C to +105⁰C.
