- 14-bit resolution with 0.0122% maximum linearity error delivers precision measurement accuracy for sensor and instrumentation designs
- Maximum conversion time of 8.89 µs enables sampling rates up to 112 kSPS for dynamic signal acquisition
- Analog input range of -0.9 V to 1.8 V supports direct connection to single-supply signal-conditioning amplifiers
- Compact 8-pin VSSOP package minimizes PCB footprint for space-constrained data-acquisition modules
- Successive approximation register (SAR) architecture provides low latency and deterministic conversion timing
What is ADS8324EB/2K5 used for?
The ADS8324EB/2K5 is well suited for precision industrial data acquisition systems, portable medical instruments, and programmable logic controllers where a single-channel 14-bit ADC must digitize low-voltage analog signals with high linearity. Its low-voltage input range and compact VSSOP package make it an excellent choice for battery-powered sensor nodes and wearable medical monitors that acquire signals from pressure, temperature, or strain-gauge transducers conditioned to the -0.9 V to 1.8 V range. The device is also used in automated test equipment and process control instrumentation where 14-bit accuracy and sub-10 µs conversion time enable fast closed-loop feedback.

Frequently Asked Questions
What resolution and conversion speed does ADS8324EB/2K5 provide for industrial sensor digitization?
The ADS8324EB/2K5 provides 14-bit resolution with a maximum conversion time of 8.89 µs, corresponding to a maximum sample rate of approximately 112 kSPS. This resolution gives 16384 quantization levels, enabling measurement of sensor signals to better than 0.01% of full scale. The SAR architecture ensures deterministic per-conversion timing with no pipeline delay, making it suitable for real-time closed-loop control in industrial systems.
What input voltage range does ADS8324EB/2K5 accept, and how should the front-end amplifier be designed?
The ADS8324EB/2K5 accepts analog input voltages from -0.9 V to 1.8 V, a 2.7 V total span. This asymmetric range requires a signal-conditioning amplifier that biases the input signal to place the midscale voltage near 0.45 V. A single-supply op-amp such as OPA340 or OPA344 can be used to offset and scale a 0 V to 5 V sensor signal down to the -0.9 V to 1.8 V window before connecting to the 1-channel ADS8324 input.
How does the 14-bit linearity of ADS8324EB/2K5 compare to 12-bit ADCs for precision process control?
The ADS8324EB/2K5 achieves 0.0122% maximum integral non-linearity (INL) error, equivalent to approximately ±2 LSB at 14 bits. A 12-bit ADC with similar LSB error would represent only 0.05% linearity. This improvement allows the ADS8324 to resolve process variables such as pressure, flow, or temperature with roughly 4 times finer granularity than a 12-bit device, reducing measurement uncertainty in precision industrial control loops and calibration systems.
For a portable medical device, why is the 8-pin VSSOP package of ADS8324EB/2K5 advantageous?
The 8-pin VSSOP package measures approximately 3 mm × 3 mm with a 0.65 mm pin pitch, occupying significantly less board area than standard SOIC-8 packages at 6 mm × 5 mm. For wearable or handheld medical devices that must fit a 14-bit ADC, reference buffer, and SPI interface within a tightly constrained PCB, the VSSOP footprint allows denser placement alongside other analog components. The small thermal mass of the package also reduces reflow stress on neighboring precision analog circuits.
What packaging quantity does ADS8324EB/2K5 supply, and is it available for prototype quantities?
The '/2K5' suffix in ADS8324EB/2K5 denotes a tape-and-reel quantity of 2500 pieces per reel, suitable for medium-to-high volume production. For prototype and engineering sample quantities, Texas Instruments and authorized distributors typically offer cut-tape options of 10 to 100 pieces, allowing engineers to evaluate the 14-bit, 8-pin VSSOP ADC before committing to full-reel purchase. Checking distributor stock for the ADS8324EB/250 (250-piece reel) can also provide a lower minimum order option.
