LTC1605CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1605CG#TRPBF is a 16-bit, 100ksps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 5V supply with typical power dissipation of 55mW. The device features an industry-standard ±10V bipolar input range and includes an internal sample-and-hold, precision reference, switched-capacitor SAR architecture, and trimmed internal clock. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2.0 LSB, guaranteed no missing codes, and a signal-to-noise ratio (SINAD) of 87.5 dB at 1kHz. It utilizes a microprocessor-compatible parallel output interface.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Multiplexed data acquisition systems
• High-speed data acquisition for PCs
• Digital signal processing applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required board layout, as the CG suffix denotes a 28-lead plastic SSOP. Confirm that the commercial temperature range (0°C to 70°C) aligns with the system's environmental operating conditions. Ensure the tape and reel packaging format is compatible with automated assembly equipment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity and low power are required in a single-supply environment. The internal reference simplifies design but may require external trimming for absolute accuracy. Consider the ±10V input range compatibility with sensor outputs. Verify that the parallel interface timing meets the host processor's requirements.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series serves as a high-performance alternative to legacy parts like the ADS7805 and AD976. The CG variant specifically provides the commercial temperature grade in a surface-mount SSOP package. This part belongs to the broader LTC1605 family, which also includes industrial grade (IG) and wide SOIC (SW) package options.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the LTC1605ACG#TRPBF (same package, A-grade linearity) and the LTC1605AIG#TRPBF (industrial temperature range). Pin-compatible alternatives such as the ADS7805 or AD976 may be considered if pinout and electrical characteristics match the specific application requirements.
