The TLC5510A is an 8-Bit, 20 MSPS ADC that combines the features of the previously announced TLC5510 with a wider 4-Volt analog input range.

The TLC5510A combines low-power with video speed and high accuracy in the industry standard pinout similar to the TLC5510, but features a 4-V (instead of a 2-Volt) analog input range. The wide 4 V input range allows the system designer to gain the signal up above common mode noise of the system board.

The TLC5510A is implemented with a multi-stage, semi-flash architecture that provides video speed conversion rates (20 MSPS) and significantly lower power consumption and cost than traditional flash converters. This architecture also provides excellent linearity accuracy with a Differential Non- Linearity (DNL) of ± 0.5 LSB and Integral Non-Linearity (INL) of ± 0.75 LSB. Like the TLC5510, the TLC5510A is an excellent choice for both Nyquist based and Correlated Double Sample systems. The analog input full power bandwidth (14 MHz at –1 dB) of the TLC5510A ensures full signal power out to the Nyquist frequency. In correlated double sample applications, like those found in CCD imaging systems, the analog input stage allows an analog input range of 0 to 4 V, thus eliminating the need to level shift the signal.

Other features include an inherent sample and hold, 3-State digital outputs, an internal reference network that will provide a standard video 2 V full range with a V DDA of 5 V and (like all members of the TLC55xx family) immunity to latch-up problems if V_DDA and V_DDD are not equal. The TLC5510A operates from a single 5-V supply and typically dissipates only 90 mW of power. The TLC5510A is avail- able in a 24-pin SOIC package.
