LTC1605IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605IG#PBF 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 a ±10V bipolar input range and integrates a sample-and-hold circuit, precision reference, switched-capacitor SAR architecture, and internal clock. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2.0 LSB, a signal-to-noise ratio (SINAD) of 86dB typ, and guaranteed no missing codes over the industrial temperature range (-40°C to +85°C). It utilizes a microprocessor-compatible parallel output interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the design requirements, as the IG suffix denotes a 28-lead SSOP. Confirm that the operating temperature range of -40°C to +85°C aligns with the system environment. Ensure the parallel interface timing constraints are met by the host controller. Check for lead-free compliance markings on the component body.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution, low-power ADC is required for single-supply applications. It serves as an improved second source for ADS7805 and AD976. Consider the internal reference accuracy; if higher temperature stability is needed, an external reference can be applied to the REF pin. Ensure the driving source impedance is low enough to meet the acquisition time requirements.

Analog To Digital Converters (ADC) Part Context

The LTC1605 belongs to the Linear Technology (now Analog Devices) family of precision data converters. This specific part number represents the industrial grade version in a plastic SSOP package. It is designed to replace older generation ADCs while offering lower power consumption and integrated functionality, reducing the need for external components like clocks and references.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the LTC1605 as an improved second source for the ADS7805 and AD976. Verify pin compatibility and timing parameters before substitution. Other parts in the LTC1605 series offer different temperature grades or packaging options.
