Applications
The ADS7808UE4 is suited for precision industrial data acquisition systems that must digitize ±10 V sensor outputs from thermocouples, strain gauges, and pressure transducers without additional signal conditioning. Its 12-bit resolution and low linearity error make it a strong fit for process-control instrumentation, programmable logic controllers, and analog I/O modules where measurement accuracy is critical. Medical and scientific instruments also benefit from its wide bipolar input range and fast 8 µs conversion time.

Frequently Asked Questions
What is the resolution and input voltage range of ADS7808UE4?
The ADS7808UE4 is a 12-bit ADC with a bipolar analog input range of ±10 V (−10 V to +10 V). This wide range allows it to directly digitize industrial-level signals from sensors such as strain gauges and thermocouples without additional level-shifting circuitry, simplifying system design and reducing component count.
How fast can ADS7808UE4 convert an analog signal, and what throughput rate does that support?
ADS7808UE4 has a maximum conversion time of 8 µs per sample, which translates to a maximum throughput of approximately 125 kSPS (kilo-samples per second). This speed is sufficient for most industrial process-control feedback loops and audio-frequency measurement tasks, while the successive-approximation architecture keeps power consumption low.
How does the 0.022% linearity error of ADS7808UE4 compare to general-purpose ADCs in precision measurement?
A maximum linearity error of 0.022% (EL) over the full ±10 V bipolar input range equals roughly ±0.9 LSB at 12-bit resolution, which is well within the performance needed for calibrated industrial instrumentation. Many general-purpose 12-bit ADCs specify ±1 LSB or higher linearity error, so the ADS7808UE4 is a better choice when measurement accuracy over the full input span is critical.
Can ADS7808UE4 be used in a multi-channel data acquisition system, and what external components are required?
The ADS7808UE4 has 1 analog input channel, so a multi-channel system requires an external analog multiplexer to switch between sensor inputs before the ADC. A typical 8-channel system pairs it with a device such as the CD74HC4051 8-to-1 mux and runs at up to 125 kSPS aggregate, with each channel sampled at 15.6 kSPS. The SOIC-20 package and standard SPI-compatible serial interface simplify integration into existing DAQ board designs.
