description (continued)
The TLV1544 has four analog input channels while the TLV1548 has eight analog input channels. The
TLV1544C and TLV1548C are characterized for operation from 0°C to 70°C. The TLV1544I and TLV1548I are
characterized for operation over the full industrial temperature range of –40°C to 85°C. The TLV1548M is
characterized for operation over the full military temperature range of –55°C to 125°C.

). RΘ
JA
values are derived from Texas Instruments
characterization data. Thermal resistance is not production tested and values are given for informational purposes only.
