DS21700D-page 3 MCP3301 1.0 ELECTRICAL CHARACTERISTICS Maximum Ratings* VDD........................................................................ 7.0V All inputs and outputs w.r.t. VSS .....-0.3V to VDD +0.3V Storage temperature .......................... -65°C to +150°C Ambient temp. with power applied ..... -65°C to +125°C Maximum Junction Temperature ....................... 150°C ESD protection on all pins (HBM) 4kV *Notice: Stresses above those listed under “Maximum ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. ELECTRICAL SPECIFICATIONS Electrical Characteristics: Unless otherwise noted, all parameters apply at VDD = 5V, VSS = 0V, and VREF = 5V. Full differential input configuration (Figure 1-5) with fixed common mode voltage of 2.5V. All parameters apply over temperature with TAMB = -40°C to +85°C (Note 7). Conversion speed (FSAMPLE) is 100 ksps with FCLK = 17*FSAMPLE Parameter Symbol Min Typ Max Units Conditions Conversion Rate Maximum Sampling Frequency FSAMPLE — — 100 ksps See FCLK specifications (Note 8) Conversion Time tCONV 13 CLK periods Acquisition Time tACQ 1.5 CLK periods DC Accuracy Resolution 12 data bits + sign bits Integral Nonlinearity INL — — ±0.5 ±1 ±1 ±2 LSB MCP3301-B MCP3301-C Differential Nonlinearity DNL — ±0.5 ±1 LSB Monotonic with no missing codes over temperature Positive Gain Error -3 -0.75 +2 LSB Negative Gain Error -3 -0.5 +2 LSB Offset Error -3 +3 +6 LSB Dynamic Performance Total Harmonic Distortion THD — -91 — dB Note 3 Signal to Noise and Distortion SINAD — 78 — dB Note 3 Spurious Free Dynamic Range SFDR — 92 — dB Note 3 Common-Mode Rejection CMRR — 79 — dB Note 6 Power Supply Rejection PSR — 74 — dB Note 4 Note 1: This specification is established by characterization and not 100% tested. 2: See characterization graphs that relate converter performance to VREF level. 3: VIN = 0.1V to 4.9V @ 1 kHz. 4: VDD = 5V DC ±500 mVP-P @ 1 kHz, see test circuit Figure 1-4. 5: Maximum clock frequency specification must be met. 6: VREF = 400 mV, VIN = 0.1V to 4.9V @ 1 kHz 7: MSOP devices are only specified at 25°C and +85°C. 8: For slow sample rates, see Section 5.2.1 “Maintaining Minimum Clock Speed” for limitations on clock frequency. 9: 4.5V - 5.5V is the supply voltage range for specified performance |
