The TLC876 is a single-supply, 10-bit, 20 MSPS analog-to-digital converter (ADC) which allows designers to reduce board space, lower power dissipation, improve bus efficiency, increase flexibility and lower system cost. This ADC's speed and resolution make it ideal in digital video systems, digital cameras, scanners, communications systems and other cost-sensitive, high performance applications.

The device, designated the TLC876, is pin compatible with the current market alternative and offers several key improvements. The TLC876's power consumption is only 107-mW, 33 percent lower than competitive device. Designers experiencing bus delays will find the TLC876 significantly reduces enable and disable times (5 ns vs. 150 ns), improving bus efficiency and system throughput.

The TLC876 analog input has been designed to allow inputs as low as ground. This permits the system designer to eliminate level shifting stages prior to the ADC, saving board space and cost. Additionally, the reference input impedance is two times higher, reducing the drive requirements and cost of the reference drive circuitry. The TLC876 guarantees differential non-linearity (DNL) of less than 1-LSB and delivers 54 dB of signal-to-noise ratio (SNL).

The TLC876 features three-state outputs, and both inputs and outputs are compatible with 3-V and 5-V logic. The TLC876 is available in 28-pin SOIC or 28-pin SSOP packaging.
