DESCRIPTION
The ADS61JB23 is a high-performance, low-power, single channel analog-to-digital converter with an integrated
JESD204A output interface. Available in a 6 mm x 6 mm QFN package, with both single-lane and dual-lane
output modes, the ADS61JB23 offers an unprecedented level of compactness. The output interface is compatible
to the JESD204A standard, with an additional mode (as per IEEE Std 802.3-2002 part3, Clause 36.2.4.12) to
interface seamlessly to the TI TLK family of SERDES transceivers. Equally impressive is the inclusion of an on-
chip analog input buffer, providing isolation between the sample/hold switches and higher and more consistent
input impedance.
The ADS61JB23 is specified over the industrial temperature range (–40°C to 85°C).
