LTC1603IG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1603IG#TRPBF is a high-speed, 16-bit sampling analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 250ksps with a typical power dissipation of 220mW using ±5V supplies. The device features a differential input sample-and-hold circuit with a –2.5V full-scale input range and a 5MHz full-power bandwidth. Key performance metrics include a typical Signal-to-Noise plus Distortion (S/(N+D)) ratio of 90dB and Total Harmonic Distortion (THD) of –100dB. It integrates an internal reference and offers two shutdown modes: Nap (7mW) and Sleep (10mW). The component is housed in a 36-lead SSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation corresponds to the industrial temperature range of –40°C to +85°C. Ensure supply voltages are strictly maintained within ±5V nominal limits to prevent damage. Check for RoHS compliance status as per current manufacturer documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low distortion at moderate sampling rates. The differential input architecture is suitable for rejecting common-mode noise in noisy environments. Consider the internal reference stability if external precision references are not available. Evaluate the 250ksps throughput against system timing requirements for microprocessor or DSP interfacing.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1603 family of high-speed ADCs. It is pin-compatible with the LTC1604 and LTC1608, which offer different resolutions or speeds. The 'IG' suffix denotes the industrial temperature range variant, while '#TRPBF' specifies the reel packaging and lead-free finish.

Analog To Digital Converters (ADC) Replacement Considerations
