Overview
The TLE2062CDR is a dual, low-power JFET-input operational amplifier produced by Texas Instruments. It is part of the TLE206x series, which doubles the bandwidth of earlier generation TL06x and TL03x BiFET families without significantly increasing power consumption. The TLE2062CDR features the Texas Instruments Excalibur process, offering a lower noise floor compared to its predecessors. This amplifier is designed for high-output drive and is suitable for applications requiring good ac characteristics, low power, and high output drive.

Q & A
- What is the bandwidth of the TLE2062CDR?
The bandwidth of the TLE2062CDR is 2 MHz, which is twice that of the earlier TL06x and TL03x Operational Amplifiers.
- What is the typical supply current per channel for the TLE2062CDR?
The typical supply current per channel is 290 µA.
- What is the input offset voltage long-term drift for the TLE2062CDR?
The input offset voltage long-term drift is 0.04 µV/mo.
- What is the common-mode input voltage range for the TLE2062CDR?
The common-mode input voltage range is -1.6 to 4 V at both 25°C and full range.
- What is the maximum positive peak output voltage swing for the TLE2062CDR?
The maximum positive peak output voltage swing is 3.5 V at RL = 10 kΩ and 25°C, and 3.3 V at full range.
- What is the output current capability of the TLE2062CDR?
The output current capability is ±80 mA.
- Is the TLE2062CDR pin-compatible with other TI BiFETs?
Yes, the TLE2062CDR is pin-compatible with other TI BiFETs, allowing it to be used to double the bandwidth of TL06x and TL03x circuits or reduce power consumption of TL05x, TL07x, and TL08x circuits.
- What are the key advantages of using JFET-input transistors in the TLE2062CDR?
The JFET-input transistors provide inherently higher input impedance without sacrificing the output drive associated with bipolar amplifiers.
- Can the TLE2062CDR be used in single-supply systems?
Yes, but care must be taken to observe common-mode input voltage limits and output swing. DC biasing of the input signal is required, and loads should be terminated to a virtual ground node at mid-supply.
- What is the operating temperature range for the TLE2062CDR?
The operating temperature range is 0 to 70°C).
