TSL1018IFT

Overview

The TSL1018IFT is an obsolete 19-channel buffer designed for TFT-LCD gamma correction. It operates on a single supply voltage ranging from 5.5V to 16.8V with a typical operating current of 8mA at 25°C. The device features a bandwidth of 3.5MHz and includes one high-output COM amplifier capable of delivering ±150mA. Buffers A and B support positive single-supply inputs for common mode voltage, suitable for highest gamma voltages. Buffers C through R and the COM amplifier utilize negative single-supply inputs for lowest gamma voltages. It is housed in a 7x7mm TQFP48 ePad package and functions within an industrial temperature range of -40°C to +95°C.

Feature Summary

• Provides 18 standard buffers plus one dedicated high-current COM amplifier for reference voltage buffering.
• Features distinct input configurations: Amplifiers A and B accept positive single-supply inputs for high-level gamma voltages, while C through R and the COM amplifier use negative single-supply inputs for low-level voltages.
• Delivers high output current capability up to ±150mA via the COM buffer to drive display loads effectively.

Applications

• TFT liquid crystal display (LCD) panels
• Gamma correction reference voltage buffering

Procurement Notes

Verify component status as this part is listed as obsolete by STMicroelectronics. Confirm availability through secondary distributors or surplus channels. Ensure the specific suffix 'IFT' corresponds to tape and reel packaging if required for automated assembly processes. Validate that the TQFP48 ePad footprint matches existing board designs before procurement.

Selection Notes

Select this component when designing TFT-LCD drivers requiring precise gamma voltage generation. The split input architecture allows handling both high and low gamma levels efficiently. Consider the 3.5MHz bandwidth and ±150mA COM output current for driving capacitive LCD loads. Verify thermal management requirements given the TQFP48 ePad package characteristics and power dissipation limits under maximum load conditions.
