LTC1605IN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605IN#PBF is a 16-bit, 100ksps sampling analog-to-digital converter (ADC) housed in a 28-lead PDIP package. It operates from a single 5V supply with typical power dissipation of 55mW. The device features a ±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 LSB, a signal-to-noise ratio (SINAD) of 87.5 dB at 1kHz, and full-scale error of ±0.25%. It provides a microprocessor-compatible 16-bit parallel output interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the design requirements, as the IN suffix denotes a 28-lead PDIP. Confirm that the operating temperature range of –40°C to +85°C aligns with the application environment. Ensure the board layout supports separate analog and digital ground planes to maintain specified performance levels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution, low-power ADC is required for single-supply systems. The internal reference simplifies design but may require external trimming for absolute accuracy. Consider the parallel interface complexity versus serial alternatives if pin count is constrained. Verify input impedance matching for the source driving the ±10V range.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series includes variants in SSOP and SO Wide packages. The IN suffix specifically identifies the industrial grade version in a plastic dual in-line package. Other family members like the LTC1605A offer tighter linearity specifications. This part serves as a direct replacement for legacy devices such as the ADS7805 and AD976.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitutes include the ADS7805 and AD976. Verify pin compatibility and electrical parameter alignment before substitution.
