ADS7805UB/1K

Analog To Digital Converters (ADC) Overview

The ADS7805UB/1K is a 16-bit successive approximation register (SAR) analog-to-digital converter in a 28-pin SOIC package. It features a single-ended ±10V input range and operates from a single +5V supply with power dissipation under 100mW. The device provides a throughput rate of 100kHz, ensuring full specification over the industrial temperature range of –25°C to +85°C. Key performance metrics include a minimum Signal-to-Noise and Distortion Ratio (SINAD) of 86dB at a 20kHz input frequency and a maximum Integral Nonlinearity (INL) error of ±3.0 LSBs. It utilizes a parallel data interface with 3-state output drivers.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix /1K corresponds to the tape and reel packaging containing 1000 units per manufacturer specifications. Confirm the UB designation indicates the specific linearity grade (±3 LSB INL) and SOIC-28 package variant. Ensure compatibility with existing board layouts for the DW package footprint.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 100kHz throughput are required within a single-supply environment. The parallel interface necessitates multiple microprocessor I/O lines; consider serial alternatives if pin count is constrained. Verify that the –25°C to +85°C industrial temperature range meets the operational requirements of the target application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7805 family of CMOS SAR ADCs. It is pin-compatible with the 12-bit ADS7804, facilitating design upgrades. The device integrates a sample-and-hold circuit, internal reference buffer, and clock logic, reducing external component count compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7805U/1K: Identical electrical specifications and functionality; differs only in tube versus tape-and-reel packaging quantity.
