Key Features

12-bit resolution, SAR architecture

8 single-ended inputs with true simultaneous sampling (per-channel S/H)

Up to 650 kSPS throughput

SPI (serial) and parallel interface options

Internal or external reference supported

Analog supply 5 V; digital supply 2.7–5.5 V for easy logic-level matching

Wide operating temperature: -40°C to 125°C

Surface-mount 64-LQFP (10 x 10 mm)

RoHS3 compliant

Key Advantages

Synchronized capture across 8 channels for time-aligned measurements

Choose serial or parallel interface to match MCU/FPGA resources

5 V analog domain improves input dynamic range for 12-bit systems

Works reliably in harsh industrial temperature ranges

LQFP package is easy to assemble, inspect, and rework

Internal reference can simplify BOM; external reference allows precision calibration

Compatible with common 3.3 V or 5 V digital logic on the IO side

Packaging

Shipping packaging: Tray

IC package: 64-LQFP (Low-Profile Quad Flat Package)

Body size: 10 mm × 10 mm nominal; low-profile height (typical around 1.4 mm; see datasheet for exact)

Pin count and pitch: 64 gull-wing leads, typically 0.5 mm pitch

Materials: Molded epoxy encapsulation, copper leadframe, matte tin lead finish (typical RoHS)

Mounting: Surface mount (SMT)

Pin configuration overview: 8 analog inputs (IN0–IN7), reference pins (internal/external options), SPI/parallel digital IO pins, AVDD 5 V, DVDD 2.7–5.5 V, grounds

Thermal characteristics: No exposed thermal pad; thermal resistance values are typical for LQFP-64 and depend on PCB stack-up. Follow datasheet guidance for θJA/θJC and copper area for heat spreading.

Electrical properties summary: 12-bit; 650 kSPS; single-ended inputs; SAR architecture with per-channel S/H; SPI or parallel interface; internal/external reference; AVDD 5 V; DVDD 2.7–5.5 V
