高電圧、汎用アンプ内蔵、超小型±15Vディジタルポテンショメータ
SUNNYVALE, CA-November 1, 2002-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX5436-MAX5439 128-step, high-voltage digital potentiometers available in a 5mm x 3mm µMAX package. These ICs are half the size of comparable devices in an 8-pin SO. The MAX5437/MAX5439 include a general-purpose, on-chip, high-voltage, uncommitted operational amplifier, which provides additional reductions in board space and cost.
These new digital pots utilize dual operating voltages of ±5V to ±15V, or single operating voltages, such as 0 to +10V, 0 to +15V, or 0 to +30V. The MAX5436-MAX5439 are excellent for liquid crystal display (LCD) contrast adjustment or high-voltage trimming applications. Other features include low 35ppm/°C end-to-end and 5ppm/°C ratiometric resistor temperature coefficients, a 3-wire SPI™/QSPI™/MICROWIRE™-compatible serial interface, power-on reset to midscale, and an amplifier shutdown mode.
The MAX5436/MAX5437 are available in 50kΩ resistances and the MAX5438/MAX5439 in 100kΩ resistances. Prices for the MAX5436/
MAX5438 without the on-chip amplifier in a µMAX package are $0.92 (100,000-up, FOB USA). Prices for the MAX5437/MAX5439 with the on-chip amplifier in a TSSOP package start at $1.24 (100,000-up, FOB USA).
