ON Semiconductor Introduces Industry's First Ultra-Low Single Supply Voltage Op Amps for Handheld Products; Multi-Functional Op Amps Can be Powered From Single Battery Cell
PHOENIX--Dec. 20, 2000--ON Semiconductor , a leading provider of power management and broadband integrated circuits that enable mobile communication and power the Internet, Wednesday announced the availability of the industry's first and only ultra-low voltage operational amplifiers (op amps) that can be powered from a single NiCd, NiMH, or alkaline battery cell.The MC33501 and MC33503, two one-volt SMARTMOS(TM) single rail-to-rail operational amplifiers, offer designers a cost-effective way to improve performance and increase the operational life of battery powered handheld systems, such as cellular phones, personal digital assistants and mini disc players.
"The MC33501 and MC33503 are currently the only op amps in the industry that operate at a supply voltage as low as 0.9 volts and are guaranteed and specified at one volt," said Kent Yancik, analog marketing engineer at ON Semiconductor.
"The cores for microprocessors and DSPs are down to 0.9 volts and these op amps, which are the building blocks of analog circuitry, support the trend towards these lower operating voltage levels. The introduction of these op amps reinforces ON Semiconductor's commitment to delivering key value added analog ICs that enable mobile electronics."
Unique in their ability to provide low rail-to-rail performance on both the input and output, the MC33501 and MC33503 provide good bandwidth versus quiescent current trade-off, and are fully operational at 0.9 volts. This enables the devices to function at higher frequencies for a given current level.
With fully specified performance over a one-volt to seven-volt range, both devices feature rail-to-rail input and output at one volt. Additionally, both devices operate right up to 0.9 volts, the discharge state of a single cell NiCd battery.
These op amps can be used for multiple functions such as driving capacitive loads, voltage generation, and inverting and non-inverting amplification. They are equipped with an "on demand" base current cancellation amplifier which allows the devices to consume very little current when the output stage is in quiescent mode.
The MC33501 and MC33503 op amps are available in a TSOP-5 package and are each configured with one pin-out. Pricing for the MC33501SNT1 and the MC33503SNT1 is suggested at $0.43 per 12K units.
