ADC364x 14-bit, 10-MSPS to 65-MSPS, Low-Noise, Low Power Dual Channel ADC

1 Features

3 Description

•

Dual channel

14-bit 10/25/65 MSPS ADC

Noise floor: –155 dBFS/Hz

Ultra-low power with optimized power scaling:

29 mW/ch (10 MSPS) to 72 mW/ch (65 MSPS)

Latency: 1 clock cycle

The ADC364x family of devices are low-noise, ultra-

low power, 14-bit, 10-MSPS to 65-MSPS dual-

channel, high-speed analog-to-digital converters

(ADCs). Designed for low power consumption, these

devices deliver a noise spectral density of –155

dBFS/Hz, combined with excellent linearity and

dynamic range. The ADC364x offers very good dc

precision, together with IF sampling support, which

make the device an excellent choice for a wide range

of applications. High-speed control loops benefit from

the short latency of only one clock cycle. The ADC

consumes only 72 mW/ch at 65 MSPS, and power

consumption scales well with lower sampling rates.

14-Bit, no missing codes

INL: ±0.6 LSB; DNL: ±0.2 LSB

Reference: external or internal

Industrial temperature range: –40°C to +105°C

On-chip digital filter (optional)

– Decimation by 2, 4, 8, 16, 32

– 32-bit NCO

DDR and Serial CMOS interface

Small footprint: 40-VQFN (5 mm × 5 mm) package

Single 1.8-V supply

Spectral performance (f_IN= 5 MHz):

– SNR: 79.0 dBFS

– SFDR: 93-dBc HD2, HD3

– SFDR: 101-dBFS worst spur

Spectral performance (f_IN= 64 MHz):

– SNR: 74.0 dBFS

The ADC364x use a DDR or serial CMOS interface to

output the data offering lowest power digital interface,

together with flexibility to minimize the number of

digital interconnects. These devices are a pin-to-pin

compatible family with different speed grades. These

devices support the extended industrial temperature

range of –40 to +105⁰C.
