Description

The AD5371 contains 40 14-bit DACs in a single 80-lead LQFP or 100-ball CSP_BGA. The device provides buffered voltage outputs with a span of 4× the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs. Three offset DACs allow the output range of the groups to be adjusted. Group 0 can be adjusted by Offset DAC 0, Group 1 can be adjusted by Offset DAC 1, and Group 2 to Group 4 can be adjusted by Offset DAC 2. The AD5371 offers guaranteed operation over a wide supply range, with VSSfrom −16.5 V to −4.5 V and VDDfrom 9 V to 16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.

Part Number: ADS42JB69

Function: Dual, 16-Bit, 250MSPS ADC with JESD204B Interface

Package: VQFN 64 Pin Type

Manufacturer: Texas Instruments

Pinouts:

Description

The ADS42JB69 and ADS42JB49 are high-linearity, dual-channel, 16- and 14-bit, 250-MSPS, analog-to-digital converters (ADCs). These devices support the JESD204B serial interface with data rates up to 3.125 Gbps.

The buffered analog input provides uniform input impedance across a wide frequency range while minimizing sample-and-hold glitch energy making it easy to drive analog inputs up to very high input frequencies. A sampling clock divider allows more flexibility for system clock architecture design.

The devices employ internal dither algorithms to provide excellent spurious-free dynamic range (SFDR) over a large input frequency range.

Features

1. Dual-Channel ADCs

2. 14- and 16-Bit Resolution

3. Maximum Clock Rate: 250 MSPS

4. Analog Input Buffer with High-Impedance Input

5. Flexible Input Clock Buffer : Divide-by-1, -2, and -4

6. Differential Full-Scale Input: 2 VPP and 2.5 VPP (Register Programmable)

7. Power Dissipation : 850 mW/Ch

8. Aperture Jitter : 85 fS rms

9. Channel Isolation : 100 dB
