APPLICATIONS ADC drivers High performance audio Instrumentation amplifier building blocks Level translators Automatic test equipment Sine/cosine encoders GENERAL DESCRIPTION The AD8273 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier (G = 1/2 or 2), inverting amplifier (G = 1/2 or 2), or noninverting amplifier (G = 11/2 or 3). The AD8273 operates on both single and dual supplies and only requires 2.5 mA maximum supply current for each amplifier. It is specified over the industrial temperature range of -40C to +85C and is fully RoHS compliant. Table 1.

At approximately 150C, which is the glass transition temperature, the plastic changes its properties. Even temporarily exceeding this temperature limit may change the stresses that the package exerts on the die, permanently shifting the parametric performance of the amplifiers. Exceeding a temperature of 150C for an extended period can result in a loss of functionality. The AD8273 has built-in, short-circuit protection that limits the output current to approximately 100 mA (see Figure 2 for more information). While the short-circuit condition itself does not damage the part, the heat generated by the condition can cause the part to exceed its maximum junction temperature, with corresponding negative effects on reliability. 2.0 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Specifications that depend on the resistor matching, such as gain drift, common-mode rejection, and gain accuracy, are better than can be achieved with standard discrete resistors. The positive and negative input terminals of the AD8273 op amp are not pinned out intentionally. Keeping these nodes internal means their capacitance is considerably lower than it would be in discrete designs. Lower capacitance at these nodes means better loop stability and improved common-mode rejection vs. frequency. -IN1 12 6k 12k 2 OUT1 13 +IN1 -IN2 14 6k 12k 3 10 6k 12k 6 9 +IN2 8 6k 12k OUT2 5 06981-016 The AD8273 has two channels, each consisting of a high precision, low distortion op amp and four trimmed resistors. Although such a circuit can be built discretely, placing the resistors on the chip offers advantages to board designers that include better dc specifications, better ac specification, and lower production costs. VOUT = 2 (VIN+ - VIN-) Figure 40. Difference Amplifier, G = 2 IN1 The internal resistors of the AD8273 lower production costs. One part rather than several is placed on the board, which improves both board build time and reliability. 2 12k 6k 12 13 14 OUT1 6k 3 12k CONFIGURATIONS The AD8273 can be configured in several different ways; see Figure 39 to Figure 46. Because these configurations rely on the internal, matched resistors, these configurations have excellent gain accuracy and gain drift. IN2 6 12k 6k 10 9 8 OUT2 6k 5 12k Use a stable dc voltage to power the AD8273. Noise on the supply pins can adversely affect performance. Place a bypass capacitor of 0.1 F between each supply pin and ground, as close to each pin as possible. Also, use a tantalum capacitor of 10 F between each supply and ground. It can be farther away from the AD8273 and typically can be shared by other precision integrated circuits. The AD8273 is specified at 15 V, but it can be used with unbalanced supplies as well, for example, -VS = 0 V, +VS = 20 V. The difference between the two supplies must be kept below 36 V. 06981-013 POWER SUPPLIES VOUT = -1/2 VIN Figure 41.
