Overview
The ADS8353IRTER, produced by Texas Instruments, is a high-performance, 16-bit, 600-kSPS (kilosamples per second), dual-channel, simultaneous-sampling analog-to-digital converter (ADC). This device is part of a family of pin-compatible ADCs that include the ADS7853 and ADS7253, offering different resolution options. The ADS8353IRTER supports both single-ended and pseudo-differential analog inputs, making it versatile for various applications.
It features excellent DC and AC performance, with a 16-bit no-missing-codes (NMC) resolution, ±2.5-LSB maximum integral nonlinearity (INL), and a signal-to-noise ratio (SNR) of 89 dB. The device also includes dual, programmable, and buffered 2.5-V internal reference sources, which can be used for system-level gain calibration.
The ADS8353IRTER is fully specified over the extended industrial temperature range of –40°C to 125°C and is available in compact WQFN-16 (3-mm × 3-mm) and TSSOP-16 packages.
