Description

ADS8344N is a Texas Instruments 16-bit, four-channel multiplexed ADC. It uses a SAR (successive-approximation) architecture with an internal sample-and-hold and a SPI-compatible serial interface (CS, SCLK, DIN, DOUT) for easy MCU integration. The four inputs can be used single-ended or differential, and channels are scanned in sequence. Designed for low power and compact packaging, it’s suitable for data acquisition, instrumentation, sensors, and control systems. It requires an external reference and operates from a single supply within TI’s recommended range. The N suffix denotes a specific package variant. For exact specs (input range, noise, data rate, and power), see the datasheet.

Package

ADS8344N is available in a 28-pin plastic package — typically LQFP-28 or TSSOP-28.

Pinout

- Pin count: 28 pins (N-package).
- Function: 4-channel, 16-bit analog-to-digital converter with a serial SPI-compatible interface. It accepts four analog inputs (IN0–IN3), uses external reference (VREF) with separate analog/digital supplies (AVDD/DVDD), and provides digital data via DIN/DOUT with SCLK and CS. Conversion is controlled by CONVST (and LDAC as applicable); includes analog/digital grounds (AGND/DGND).

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
Type of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits.

Application

Common application areas for ADS8344N include:
- Industrial data acquisition and control
- Medical instrumentation and patient monitoring
- Automotive sensing and ECUs
- Instrumentation, test, and benchtop equipment
- Power/energy monitoring and metering
- Environmental and process monitoring
- Laboratory research instruments and data loggers

Equivalent

ADS8344N is a 16‑bit, 4‑channel multiplexed ADC with SPI interface from Analog Devices. There isn’t a direct one‑to‑one cross‑reference. Closest equivalents are other 16‑bit, multi‑channel SPI ADCs from Analog Devices and from TI/Microchip with similar throughput.
