What are the key features of ADS7806P?
- 12-bit successive approximation resolution with 0.022% maximum linearity error for accurate analog digitization
- Wide ±10 V input range enabling direct digitization of industrial bipolar signals without external attenuation
- Low-power CMOS design with 20 µs maximum conversion time, suitable for multi-channel scanning at rates up to 50 kSPS
What is ADS7806P used for?
The ADS7806P is ideal for industrial data acquisition systems that need to digitize bipolar analog signals in the ±10 V range directly from sensors, transmitters, or signal conditioners without external attenuation. Its 12-bit resolution and 20 µs conversion time make it suitable for medium-speed process monitoring, control loop feedback, and precision measurement instruments. The 28-pin DIP package supports prototyping and through-hole production boards in benchtop instruments, PLC analog input modules, and legacy system upgrades.

Frequently Asked Questions
Can ADS7806P directly accept ±10 V industrial sensor signals without an external attenuator?
Yes, the ADS7806P supports an analog input voltage range of -10 V to +10 V, which directly accommodates standard industrial bipolar signal levels such as ±10 V from DAC outputs, strain gauge bridges, and thermocouple amplifiers. This eliminates the need for a resistive divider or op-amp attenuator on the signal path, reducing component count by 2 to 4 parts and lowering signal chain noise in 12-bit measurement applications.
For a multi-channel data logger, how many ADS7806P channels can be scanned per second using a microcontroller?
With a maximum conversion time of 20 µs per sample, a single ADS7806P can deliver up to 50,000 samples per second (50 kSPS) on its single channel. In a multiplexed 8-channel data logger where an external MUX switches inputs before each conversion, throughput per channel drops to approximately 6,250 SPS per channel, suitable for slow-moving process variables such as temperature (0.1 Hz to 10 Hz bandwidth) or pressure measurements in industrial control systems.
Is ADS7806P suitable for replacing older 12-bit ADCs in legacy through-hole PLC analog input boards?
Yes, the ADS7806P's 28-pin DIP package and ±10 V input range align with many legacy ADC form factors used in 1990s-era PLC and industrial control boards, making it a practical drop-in replacement for discontinued parts. Its 0.022% maximum linearity error matches or exceeds the performance of older 12-bit ADCs that typically specified ±1 LSB linearity (0.024%), and its low-power CMOS process reduces supply current consumption compared to older bipolar ADC designs drawing 10 mA or more.
