description

The TLC271 operational amplifier combines a

wide range of input offset voltage grades with low

offset voltage drift and high input impedance. In

addition, the TLC271 offers a bias-select mode

that allows the user to select the best combination of power dissipation and ac performance for a particular

application. These devices use Texas Instruments silicon-gate LinCMOS technology, which provides offset

voltage stability far exceeding the stability available with conventional metal-gate processes.

TLC271, TLC271A, TLC271B LinCMOS PROGRAMMABLE LOW-POWER OPERATIONAL AMPLIFIERS SLOS090D – NOVEMBER 1987 – REVISED MARCH 2001 bias selection Bias selection is achieved by connecting the bias select pin to one of three voltage levels (see Figure 1). For medium-bias applications, it is recommended that the bias select pin be connected to the midpoint between the supply rails. This procedure is simple in split-supply applications, since this point is ground.

TLC271, TLC271A, TLC271B LinCMOS PROGRAMMABLE LOW-POWER OPERATIONAL AMPLIFIERS SLOS090D – NOVEMBER 1987 – REVISED MARCH 2001 PARAMETER MEASUREMENT INFORMATION input bias current Because of the high input impedance of the TLC271 operational amplifiers, attempts to measure the input bias current can result in erroneous readings. The bias current at normal room ambient temperature is typically less than 1 pA, a value that is easily exceeded by leakages on the test socket.

A resistive voltage divider is usually sufficient to establish this reference level (see Figure 103).

Nulling of the input off set voltage may be achieved by adjusting a 25-kΩ potentiometer connected between the offset null terminals with the wiper Connected as shown in Figure 105. The amount of nulling range varies with the bias selection.

Most oscillation problems result from driving capacitive loads and ignoring stray input capacitance.

The devices drive higher capacitive loads; however, as output load capacitance increases, the resulting response pole occurs at lower frequencies, thereby causing ringing, peaking, or even oscillation (see Figures 110, 111, and 112).

The simplest method involves the use of a pullup resistor (RP) connected from the output to the positive supply rail (see Figure 113).
