Overview
The ADS8507IBDWG4, produced by Texas Instruments, is a 16-bit, low-power, sampling analog-to-digital converter (ADC) designed for a wide range of applications. This device operates on a single 5-V supply and features a successive approximation register (SAR) architecture with an integrated sample and hold circuit, clock, reference, and data interface. It is highly versatile, supporting various input ranges including ±10 V, 4 V, and 5 V, and offers both parallel and serial data output interfaces.
The ADS8507IBDWG4 is optimized for low power consumption, with a typical power dissipation of 24 mW at 40 kSPS and a maximum power down mode of 50 µW. It is specified to operate over the industrial temperature range of -40°C to 85°C, making it suitable for harsh environments.
