Industry's First 5 Kohm Digital Potentiometers with Specified 36V Operating Voltage; Support Wide Signal Swings
CHANDLER, Ariz. --(Business Wire)--
Microchip Technology (News - Alert) Inc. (NASDAQ: MCHP), a leading provider of
microcontroller, mixed-signal, analog and Flash-IP solutions, today
expanded its 36V digital
potentiometer (digipot) portfolio with two new volatile, I2C™
(MCP45HV31-51). These are the industry's first digipots to offer a 5
kohm resistance with a specified operating voltage of 36V. Additionally,
they provide 10V to 36V analog operation and 1.8V to 5.5V digital
operation for systems requiring wide signal swings or high power-supply
voltages. The MCP45HV31-51 digipots support both 7-bit and 8-bit
resistor configurations, and a high terminal/wiper current, including
the ability to sink/source up to 25 mA on all terminal pins for driving
larger loads. These features, combined with an extended temperature
range of -40�C to +125�C, make the MCP45HV31-51 well suited for a broad
range of high-voltage and high-temperature applications, including those
in the industrial, automotive and audio markets.
The MCP45HV31's 7-bit resistor network resolution enables 127 resistors
and 128 taps, while the MCP45HV51's 8-bit configuration supports 255
resistors and 256 taps. Additionally, both digipots provide RAB
resistance options of 5, 10, 50 and 100 kohms. Both devices also feature
a 1 �A typical serial-interface inactive current, and a 2 MHz typical
bandwidth operation (-3 dB) at the 5 kohm resistance level.
"With their support of the wide operating voltages and extended
temperature ranges that are common in industrial and automotive power
supplies, these new digital potentiometers allow Microchip to address a
broad range of applications," said Bryan J. Liddiard, marketing vice
president of Microchip's Analog and Interface Products Division. "These
digipots are well suited to any application that operates on higher
TSSOP and SSOP Evaluation Board (part # TSSOP20EV) allows system
designers to quickly evaluate the operation of these new MCP45HV31-51
digipots, in their 14-pin TSSOP package option.
Pricing and Availability
Both digital potentiometers are available today for samples and volume
production, in 14-pin TSSOP and 20-pin, 5x5 mm QFN packages. The MCP45HV31
is $0.99 each and the MCP45HV51
is $1.09 each, in 5,000-unit quantities.
