LTC1594CS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1594CS#TRPBF is a micropower, 12-bit sampling analog-to-digital converter featuring a 4-channel multiplexer. It operates on a single 5V supply (4.5V to 5.5V) and typically draws 320μA during conversion, automatically powering down to 1nA between samples. The device includes a sample-and-hold circuit and serial I/O compatible with SPI, QSPI, and MICROWIRE interfaces. Key electrical parameters include a maximum differential nonlinearity of ±3/4 LSB, a maximum sampling frequency of 16.8ksps, and an input voltage range from –0.05V to VCC + 0.05V.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed ±3/4 LSB maximum differential nonlinearity
• Integrated 4-channel analog multiplexer with separate MUXOUT and ADCIN pins
• Automatic power-down mode reducing supply current to 1nA
• Serial interface compatible with standard microprocessor protocols

Analog To Digital Converters (ADC) Applications

• Battery-operated systems requiring low power consumption
• Remote data acquisition networks
• Isolated data acquisition applications
• Temperature measurement systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms the component is supplied in tape and reel packaging and is lead-free compliant. Confirm the CS suffix indicates the commercial temperature range (0°C to 70°C). Ensure the package designation matches the 16-lead narrow SO format specified for the LTC1594 variant.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a single-channel 12-bit ADC with integrated multiplexing. The device supports reduced input spans down to 1.5V, enabling high resolution for low-voltage signals. Ensure the system clock frequency remains above recommended thresholds at elevated temperatures to maintain accuracy due to sample-and-hold droop characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1594/LTC1598 family of micropower sampling A/D converters. While the LTC1598 offers an 8-channel multiplexer in a 24-pin SSOP package, the LTC1594 provides a 4-channel configuration in a compact 16-pin SO package. Both variants share identical core ADC performance and power management features.
