LTC1858IG#TRPBF

LTC1858IG#TRPBF Description

The LTC1858IG#TRPBF from Analog Devices Inc. is a high-performance 14-bit SAR ADC (Successive Approximation Register Analog-to-Digital Converter) designed for precision data acquisition systems. Housed in a compact 28-pin SSOP package and available in Tape & Reel (TR), this device integrates a single ADC with 8 configurable inputs supporting both single-ended and differential signal measurements. It operates on a 5V analog/digital supply, delivering a 100kSPS sampling rate with 1:1 sample-and-hold (S/H) to ADC ratio for accurate signal capture. The SPI-compatible interface ensures seamless communication with microcontrollers or DSPs, while its SoftSpan™ architecture allows flexible input range programming via software.

LTC1858IG#TRPBF Features

• 14-bit resolution with SAR architecture for high-accuracy conversions.
• 8-channel multiplexer supporting ±10V differential or 0V to 5V single-ended inputs.
• 100k samples/second throughput with low latency.
• Internal or external reference (2.5V default) for design flexibility.
• SPI interface for easy integration with digital systems.
• 5V single-supply operation simplifies power management.
• SoftSpan™ technology enables programmable input ranges (±10V, ±5V, 0–10V, 0–5V).
• ROHS3 compliant and REACH unaffected, suitable for environmentally conscious designs.
• MSL 1 (Unlimited) rating ensures reliability in storage and handling.
