Rail-to-Rail Operation on the Input The input voltage range is a function of the input circuit topology. There are three basic topologies that are used to design the input stage of single-supply, voltage-feedback amplifiers. The most common topology has a single differential input stage using...
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may affect device reliability. Note 2. θJA is measured at TA = 25°...
By the term universal, we mean that the accuracy is independent of the type and the operation region of the input devices. In other words, universal means that the technique is valid for any gm versus Id characteristic of the amplifier input transistors and, hence, is compatible with modern ...

Focuses on the functions of digital command control (DCC), a system designed to simplify the wiring and operation of a model-railroad layout. Hardware components included in DCC; Evolution of DCC from attempts at digital control by manufacturers; Number of bytes in DCC signal; Use of DCC...
This paper presents a current-mode common-mode feedback (CMFB) circuit with rail-to-rail operation. The CMFB is a stand-alone circuit, which can be connected to any low voltage transconductor without changing or upsetting the existing circuit. The proposed CMFB employs current mirrors, operating...
The dual MAX492, quad MAX494, and single MAX495 operational amplifiers combine excellent DC accuracy with rail-to-rail operation at the input and output. Since the common-mode voltage extends from VCC to VEE, the devices can operate from either a single supply (+2.7V to +6V) or split su...
Within the 400mV transition region PSRR, CMRR, offset voltage, and offset drift may be degraded compared to operation outside this region. For more information on de- signing with rail-to-rail input op amps, see Figure 3, Design Optimization with Rail-to-Rail Input Op Amps. FIGURE 1. ...
A low-voltage complementary metal-oxide semiconductor adapter circuit suitable for input rail-to-rail operation quasi rail-to-rail voltage-controlled resistor (VCR), rail-to-rail operational amplifier (OA) and quasi rail-to-rail second generation current conveyor. ... Tadi, Nika,Zogovi, Milena,...
For normal operation, inputs must be limited to this range. The absolute maximum input voltage is 500 mV beyond the supplies. Inputs greater than the input common-mode range but less than the maximum input voltage, while not valid, do not cause any damage to the op amp. Unlike some ...
