December 2005 Rev. 4 1/12 TS321 Low Power Single Operational Amplifier ■ Large output voltage swing: ■ 0 to 3.5V min. (@VCC = 5V) ■ Low supply current: 500µA ■ Low input bias current: 20nA ■ Low input offset voltage: 2mV max. ■ Wide power supply range: ■ Single supply: +3V to +30V ■ Dual supplies: ±1.5V to ±15V ■ Stable with high capacitive loads

Description

The TS321 is intended for cost-sensitive applications where space saving is of great importance. This bipolar op-amp offers the benefits of a reduced component size (SOT23-5 package), with specifications that match (or are better) industry standard devices (like the popular LM358A, LM324, etc.). The TS321 has an input common mode range (V icm) that includes ground, and therefore can be employed in single supply applications.

2 Absolute Maximum Ratings

Table 1. Key parameters and their absolute maximum ratings

  1. Short-circuits from the output to V CC can cause excessive heating if VCC > 15V. The maximum output current is

approximately 40mA independent of the magnitude of V CC.

  1. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base

negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.

  1. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all

amplifiers. All values are typical.

  1. Human body model, 100pF discharged through a 1.5k Ω resistor into pin of device.
  2. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external

series resistor (internal resistor < 5 Ω), into pin to pin of device.

3 Electrical Characteristics

Table 2. V cc

100 V/mV

  1. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the ou tput

so no loading change exists on the input lines.

  1. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V.

4 Macromodel

Note: Please consider following remarks before using this macromodel: All models are a trade-off between accuracy and complexity (i.e. simulation time). Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the NOMINAL performance of a TYPICAL device within SPECIFIED OPERATING CONDITIONS (i.e. temperature, supply voltage, etc.). Thus the macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main parameters of the product. Data issued from macromodels used outside of its specified conditions (Vcc, Temperature, etc) or even worse: outside of the device operating conditions (Vcc, Vicm, etc) are not reliable in any way.
