description/ordering information

The TL05x series of JFET-input operational amplifiers offers improved dc and ac characteristics over the TL07x

and TL08x families of BiFET operational amplifiers. On-chip Zener trimming of offset voltage yields precision

grades as low as 1.5 mV (TL051A) for greater accuracy in dc-coupled applications. Texas Instruments improved

BiFET process and optimized designs also yield improved bandwidth and slew rate without increased power

consumption. The TL05x devices are pin-compatible with the TL07x and TL08x and can be used to upgrade

existing circuits or for optimal performance in new designs.

BiFET operational amplifiers offer the inherently higher input impedance of the JFET-input transistors, without

sacrificing the output drive associated with bipolar amplifiers. This makes them better suited for interfacing with

high-impedance sensors or very low-level ac signals. They also feature inherently better ac response than

bipolar or CMOS devices having comparable power consumption.

The TL05x family was designed to offer higher precision and better ac response than the TL08x, with the low

noise floor of the TL07x. Designers requiring significantly faster ac response or ensured lower noise should

consider the Excalibur TLE208x and TLE207x families of BiFET operational amplifiers.

Because BiFET operational amplifiers are designed for use with dual power supplies, care must be taken to

observe common-mode input voltage limits and output swing when operating from a single supply. DC biasing

of the input signal is required, and loads should be terminated to a virtual-ground node at mid-supply. Texas

Instruments TLE2426 integrated virtual ground generator is useful when operating BiFET amplifiers from single

supplies.

The TL05x are fully specified at ±15 V and ±5 V. For operation in low-voltage and/or single-supply systems,

Texas Instruments LinCMOS families of operational amplifiers (TLC-prefix) are recommended. When moving

from BiFET to CMOS amplifiers, particular attention should be paid to the slew rate and bandwidth

requirements, and also the output loading.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
