Detailed Description

Dual-channel 12-bit high-speed ADC with pipelined architecture

125 MSPS sampling per channel with simultaneous sampling

Differential analog inputs with integrated sample-and-hold front end

LVDS parallel digital outputs for high-speed, low-noise data transfer

Internal reference for simplified design

Low-voltage operation with separate analog and digital supplies

Industrial temperature range in a compact 64-VQFN package with exposed thermal pad

Key Features

Resolution 12 bits

Channels 2 ADCs with simultaneous sampling

Sample rate 125 MSPS per channel

Architecture Pipelined

Input type Differential

Data interface LVDS parallel output bus

Reference Internal reference

Supplies Analog 1.7 V to 1.9 V, Digital 1.7 V to 1.9 V

Mounting Surface mount

Operating temperature -40 °C to +85 °C

RoHS status ROHS3 compliant

Base product number ADS4225

Supplier device package 64-VQFN 9 mm x 9 mm

Key Advantages

Two matched ADCs allow true simultaneous sampling for precise dual-channel measurements

LVDS outputs reduce EMI and support clean high-speed data transfer to FPGAs and processors

Internal reference reduces external component count and speeds up design-in

Low 1.8 V supplies lower power and simplify power architecture

Small 9 x 9 mm QFN with exposed pad saves board space and improves thermal performance

Pipelined design enables high throughput with stable linearity and dynamic performance

Differential inputs improve common-mode noise rejection and system robustness

Packaging

Type Tape and Reel TR for automated SMT assembly

Package case 64-VQFN 9 x 9 mm with exposed thermal pad VFQFN Exposed Pad

Material Lead-free molded plastic QFN over copper leadframe with matte tin plating, ROHS3 compliant

Size 9 mm x 9 mm body, low-profile QFN for dense layouts

Pin configuration 64 perimeter leads plus a large center exposed pad; route LVDS outputs, clocks, and power pins per datasheet guidance

Thermal characteristics Exposed center pad must be soldered to a grounded copper area with thermal vias to spread heat and reduce thermal resistance; follow TI layout recommendations to achieve stable operation across the full temperature range

Electrical properties Differential analog inputs, LVDS parallel outputs, separate 1.7–1.9 V analog and digital supplies; decouple each supply with low-ESR capacitors placed close to pins; adhere to ESD handling best practices

Lifecycle

Current status Active for production use based on the latest available information
