description
The TL03x series of JFET-input operational amplifiers offer improved dc and ac characteristics over the TL06x
family of low-power BiFET operational amplifiers. On-chip zener trimming of offset voltage yields precision
grades as low as 1.5 mV (TL031A) for greater accuracy in dc-coupled applications. Texas Instruments improved
BiFET process and optimized designs also yield improved bandwidths and slew rates without increased power
consumption. The TL03x devices are pin-compatible with the TL06x 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 higher input impedance makes the TL3x
amplifiers better suited for interfacing with high-impedance sensors or very low-level ac signals. These devices
also feature inherently better ac response than bipolar or CMOS devices having comparable power
consumption.
The TL03x family has been optimized for micropower operation, while improving on the performance of the
TL06x series. Designers requiring significantly faster ac response should consider the Excalibur TLE206x
family of low-power 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 midsupply. Texas
Instruments TLE2426 integrated virtual-ground generator is useful when operating BiFET amplifiers from single
supplies.
The TL03x devices 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 slew rate, bandwidth
requirements, and output loading.
The C-suffix devices are characterized for operation from 0
°
C to 70
°
C. The I-suffix devices are characterized
for operation from –40
°
C to 85
°
C. The M-suffix devices are characterized for operation over the full military
temperature range of –55
°
C to 125
°
C.
