LTC1598LCG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1598LCG#PBF is a micropower, 12-bit sampling analog-to-digital converter (ADC) featuring an 8-channel multiplexer. It operates on a single 3V supply (2.7V to 3.6V) and typically draws 160μA during conversion at 10.5ksps, dropping to 1nA in auto-shutdown mode. The device includes a sample-and-hold circuit and serial I/O compatible with SPI, QSPI, and Microwire. Key electrical specifications include ±3/4LSB maximum differential nonlinearity (DNL), ±3LSB integral linearity error, and a reference input range of 1.5V to VCC + 0.05V. It is housed in a 24-lead plastic SSOP package.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed ±3/4LSB max DNL and no missing codes
• 8-channel analog multiplexer with separate MUXOUT and ADCIN pins
• Low power consumption: 160μA typical during conversion, 1nA shutdown current
• Serial interface compatible with QSPI, SPI, and Microwire standards

Analog To Digital Converters (ADC) Applications

• Battery-operated systems
• Remote data acquisition
• Isolated data acquisition
• Pen screen digitizing
• Temperature measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free packaging compliant with RoHS directives. Confirm the CG suffix corresponds to the commercial temperature range of 0°C to 70°C. Ensure the 24-pin SSOP package dimensions match the PCB footprint requirements for the specific design implementation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low voltage operation (3V) and minimal power consumption. The LTC1598L variant is suitable where 2.7V minimum supply is required. Consider the LTC1598 (non-L version) if 5V operation or higher sampling rates up to 16.8ksps are necessary instead of the 10.5ksps limit of the L-series.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1594L/LTC1598L family of micropower sampling A/D converters. The LTC1598L specifically provides 8 channels, whereas the LTC1594L offers 4 channels. Both share similar architectural features but differ in channel count and package options (SSOP vs SO).
