LTC1591/LTC1597 are 5V single supply 14-bit and 16-bit parallel input multiplying current output DACs. Their INL and DNL are accurate to 1LSB over the industrial temperature range in both 2 and 4 quadrant multiplying modes. True 16-bit 4 quadrant multiplication is achieved with on-chip 4 quadrant multiplication resistors. These DACs also include an internal deglitcher circuit which reduces the glitch impulse to less than 2nV-s (typ). The asynchronous CLR pin resets the LTC1591/LTC1597 to zero scale and LTC1591-1/LTC1597-1 to midscale. LTC1591/LTC1597 are available in 28-pin SSOP and PDIP packages and are specified over the industrial temperature range. For serial interface 16-bit current output DACs, refer to the LTC1595/LTC1596 data sheet.
The LTC1591 and LTC1597 are pin‑compatible, 14‑bit and 16‑bit parallel‑input multiplying DACs with on‑chip 4‑quadrant resistors. They provide true 16‑bit performance, low glitch impulse (< 2 nV‑s) and a wide operating temperature range.
The devices are offered in 28‑lead SSOP and PDIP packages and include specifications such as supply voltage 4.5 V – 5.5 V, maximum junction temperature 125 °C, and typical INL of ±1 LSB. Electrical characteristics, absolute maximum ratings and typical performance graphs are detailed throughout the document.
