BUF12840AIRGER Description

Short technical summary and product information.

The Texas Instruments BUF12840AIRGER is a 12-channel gamma voltage generator designed for TFT-LCD reference drivers. It offers 10-bit resolution and the capability to read gamma voltage settings from external EEPROM.

 

This device features two independent, pin-selectable memory banks, allowing for simultaneous storage of two different gamma curves. This facilitates easy switching between curves as needed for display applications. The gamma channels provide rail-to-rail output, swinging typically to within 200mV of either supply rail with a 5mA load.

 

Operating with a supply voltage range of 9V to 20V and a digital supply of 2V to 5.5V, the BUF12840AIRGER consumes low supply current. It utilizes a two-wire interface that supports both 400kHz and 3.4MHz operation for programming. The component is housed in a 24-pin VQFN package and operates within a temperature range of -40°C to 95°C.

 

Key features include its 12 programmable gamma channels, external EEPROM read capability, and dual memory banks. The device is suitable for applications requiring precise gamma voltage generation for LCD displays.
